Question: Which members of The Clinch Mountain Boys released a recording of "Molly and Tenbrooks" in 1948?

full_context: Document 1: Molly and Tenbrooks: "Molly and Tenbrooks," also known as "The Racehorse Song," is a traditional song of the late 19th century. One of the first recordings of the song was the Carver Boys' 1929 version called "Tim Brook." The song was recorded by Bill Monroe and His Blue Grass Boys on October 28, 1947 but not released until 1949. In 1948, The Stanley Brothers released a recording of it in the Blue Grass Boys' style, marking the first recorded adoption of the bluegrass style by a second band. The song was also recorded by Steve Gillette on his self-titled debut album in 1967 in the folk style and a very different adaptation, by Gillette and Linda Albertano. Their version was later recorded by the well-known Canadian folk duo Ian and Sylvia for their album, Play One More.
Document 2: Cumberland Gap (folk song): "Cumberland Gap" is an Appalachian folk song that likely dates to the latter half of the 19th century and was first recorded in 1924. The song is typically played on banjo or fiddle, and well-known versions of the song include instrumental versions as well as versions with lyrics. A version of the song appeared in the 1934 book, "American Ballads and Folk Songs", by folk song collector John Lomax. Woody Guthrie recorded a version of the song at his Folkways sessions in the mid-1940s, and the song saw a resurgence in popularity with the rise of bluegrass and the American folk music revival in the 1950s. In 1957, the British musician Lonnie Donegan had a No. 1 UK hit with a skiffle version of "Cumberland Gap".
Document 3: Carter Family: The Carter Family is a traditional American folk music group that recorded between 1927 and 1956. Their music had a profound impact on bluegrass, country, Southern Gospel, pop and rock musicians as well as on the U.S. folk revival of the 1960s. They were the first vocal group to become country music stars. Their recordings of songs such as "Wabash Cannonball", "Can the Circle Be Unbroken", "Wildwood Flower", "Keep On the Sunny Side" and "I'm Thinking Tonight of My Blue Eyes" made these songs country standards. The latter's tune was used for Roy Acuff's "The Great Speckled Bird", Hank Thompson's "The Wild Side of Life" and Kitty Wells' "It Wasn't God Who Made Honky Tonk Angels", making the song a hit all over again in other incarnations.
Document 4: Raybon Brothers: The Raybon Brothers was a country duo from Sanford, Florida consisting of brothers Marty Raybon and Tim Raybon. Prior to the duo's inception in 1997, Marty Raybon was the lead singer of the country music band Shenandoah, having left in 1997, before rejoining in 2014.
Document 5: Lonesome Pine Fiddlers: The Lonesome Pine Fiddlers (1938- 1966) were an early bluegrass band which included such notable "first generation" bluegrass musicians as Ezra Cline, Bobby Osborne, Paul Williams, Melvin Goins, Charlie Cline, Curly Ray Cline, Larry Richardson and for a short time Jimmy Martin. The group was started by Ezra Cline and Curly Ray Cline and was originally named "Cousin Ezra and the Lonesome Pine Fiddlers". The Clines came from a large family consisting of musically talented people. Ray and Charlie's father, Charlie, was a talented banjo player and the women in the family, Geraldine and Bobbi, were great singers. For reasons unknown, Bobbi and Geraldine never joined the band on the road but often joined in at home, especially when notable Country singers, such as Bill Monroe, Lester Flatt and Earl Scruggs, and Hank Williams, came visiting. None of them ever had a music lesson yet excelled on every instrument they touched. Natives of the Gilbert Creek region of southern West Virginia, Cousin Ezra, along with brothers Ireland (Lazy Ned) and Curly Ray Cline, were part of the original Lonesome Pine Fiddlers from about 1938, a group that worked on radio at WHIS Bluefield, West Virginia. During World War II, Ned was killed in action. When the Pine Fiddlers resumed regular daily broadcasts, Charlie, who played multiple instruments, joined them on a regular basis. Charlie returned to the Fiddlers briefly before becoming a member of Bill Monroe's Blue Grass Boys. During 1952-1955, Charlie worked off and on with Monroe, recording some 38 songs, all on Decca. It has been said that he played every instrument at one time or another in the Monroe group except mandolin. Charlie spent most of 1953 back with the Lonesome Pine Fiddlers working at WJR radio in Detroit. When Ezra brought the band to Pikeville, Kentucky, in November, Charlie rejoined Bill Monroe. In 1954, Charlie did a session, playing lead guitar, with the Stanley Brothers and also another one on RCA with the Fiddlers, although he was not otherwise working with them at the time. He also worked briefly as a sideman with the Osborne Brothers, although he did not record with them. By 1958, Charlie (electric lead guitar) and his wife, Lee (electric bass), had rejoined Ezra and Curly Ray in the Lonesome Pine Fiddlers, who were experimenting with a more modern sound and working a TV show in Huntington, West Virginia, in addition to daily radio in Pikeville. In his later years, Charlie was with the Stanley Brothers. Curly Ray also played with the Stanley Brothers at a different time as their fiddler. Curly Ray was one of the best fiddlers in Bluegrass. This most talented family of musicians were the best, surpassed by none. Finally, on October 1, 2009, The Lonesome Pine Fiddlers got their due when they were inducted into the International Bluegrass Hall of Fame at the Ryman Theater (the original home of the Grand Ole Opry). Bobby Osborne, Melvin Goins and Paul Williams were there to receive the bands award. In the crowd of a sold out theater was the son of Ezra Cline, Scotty Ireland Cline, who recalled being in that same theater as a child sitting on stage and watching the Fiddlers play. (At the time, the Opry had bleachers for family just off stage). The final act of the evening at the IBMA Awards was the playing of "Pain in my Heart" by Osborne, Goins and Williams along with a Song from the Dillards, who were also inducted the same evening.
Document 6: The Stanley Brothers: The Stanley Brothers were an American bluegrass duo made up of brothers Carter Stanley (1925–1966) and Ralph Stanley (1927–2016). Ralph and Carter performed as The Stanley Brothers with their band, The Clinch Mountain Boys, from 1946 to 1966. Ralph kept the band name when he continued as a solo after Carter's death, from 1967 until his own death in 2016.
Document 7: The Everly Brothers: The Everly Brothers were an American country-influenced rock and roll duo, known for steel-string acoustic guitar playing and close harmony singing. Isaac Donald "Don" Everly (born February 1, 1937) and Phillip "Phil" Everly (January 19, 1939 – January 3, 2014) were elected to the Rock and Roll Hall of Fame in 1986 and the Country Music Hall of Fame in 2001.
Document 8: The Bailey Brothers and the Happy Valley Boys: The Bailey Brothers and the Happy Valley Boys were an American bluegrass act widely considered to be among the first to cultivate the duo harmony vocal technique widely used in modern bluegrass music today. Charlie Bailey (February 11, 1916 in Happy Valley, Tennessee, near Rogersville – March 12, 2004 in Bear, Delaware) began his musical career in 1936. His brother, Danny Bailey (December 1, 1919, Happy Valley, Tennessee – March 22, 2004, Knoxville, Tennessee), teamed up with him in 1940, and the brothers began making frequent appearances on Tennessee radio stations in the Knoxville area. Danny formed the Happy Valley Boys after Charlie joined the military in 1941. In 1944 the Happy Valley Boys relocated to Nashville, where they became members of the Grand Ole Opry, and also made regular appearances on WSM radio in Nashville. At that time, Danny was the youngest person to ever perform on the Grand Ole Opry. When Charlie returned from his military service in 1946 the brothers were reunited as a duo but only stayed in Nashville briefly before returning to radio work in Knoxville.
Document 9: Carter Stanley: Carter Glen Stanley (August 27, 1925 – December 1, 1966) was a bluegrass music lead singer, songwriter, and rhythm guitar player. He formed "The Stanley Brothers and The Clinch Mountain Boys" band together with his brother Ralph. The Stanley Brothers are generally acknowledged as the first band after Bill Monroe & the Blue Grass Boys to play in the bluegrass genre. According to some historians, their recording of "Molly and Tenbrooks" (aka "The Racehorse Song") marked the beginning of bluegrass as a genre.
Document 10: Big Rock Candy Mountain: "Big Rock Candy Mountain", first recorded by Harry McClintock in 1928, is a Bluegrass song about a hobo's idea of paradise, a modern version of the medieval concept of Cockaigne. It is a place where "hens lay soft boiled eggs" and there are "cigarette trees." McClintock claimed to have written the song in 1895, based on tales from his youth hoboing through the United States, but some believe that at least aspects of the song have existed for far longer. It is catalogued as Roud Folk Song Index No. 6696.
Document 11: Ralph Stanley: Ralph Edmund Stanley (February 25, 1927 – June 23, 2016), also known as Dr. Ralph Stanley, was an American bluegrass artist, known for his distinctive singing and banjo playing. Stanley began playing music in 1946, originally with his brother Carter as part of The Stanley Brothers, and most often as the leader of his band, The Clinch Mountain Boys.
Document 12: The Moonshiner: "The Moonshiner" is a folk song with disputed origins. It is catalogued as Roud Folk Song Index No. 4301. Some believe that the song originated in America, then later was made famous in Ireland. Others believe that it was the other way around. The Clancy Brothers stated on their recording that the song is of Irish origin, but again, this is disputed. Delia Murphy was singing it in Ireland from the late 1930s. American country music singer Tex Ritter is famous for a song of similar tune and lyrics by the title "Jack of Diamonds" from as early as 1933. Bob Dylan recorded "Moonshiner" in 1963; this version was released on "The Bootleg Series Volumes 1-3 (Rare & Unreleased) 1961-1991". The song has also been performed by Elliott Smith, Cat Power, Rumbleseat, Cast Iron Filter, Peter Rowan, Railroad Earth, Bob Forrest, Roscoe Holcomb, Uncle Tupelo, Jeffrey Foucault, The Tallest Man On Earth, Tim Hardin, Charlie Parr, Punch Brothers, Redbird, Sons of an Illustrious Father, Robert Francis, Scorpios, Ekoostik Hookah, Moriarty and Ben Holland.
Document 13: Mule Train: "Mule Train" is a popular song written by Johnny Lange, Hy Heath, Ramblin' Tommy Scott and Fred Glickman. It's a cowboy song, with the singer filling the role of an Old West wagon driver, spurring on his team of mules pulling a delivery wagon. As he goes about his work, the driver mentions the various mail-order goods he is delivering to far-flung customers. Mule Train was originally recorded by Ellis "Buz" Butler, Jr in 1947. Buz was the original writer of the song along with Fred Glickman. The original recording was released by Buz Butler on Decca records.
Document 14: Dock Boggs: Moran Lee "Dock" Boggs (February 7, 1898 – February 7, 1971) was an influential old-time singer, songwriter and banjo player. His style of banjo playing, as well as his singing, is considered a unique combination of Appalachian folk music and African-American blues. Contemporary folk musicians and performers consider him a seminal figure, at least in part because of the appearance of two of his recordings from the 1920s, "Sugar Baby" and "Country Blues", on Harry Smith's 1951 collection "Anthology of American Folk Music". Boggs was first recorded in 1927 and again in 1929, although he worked primarily as a coal miner for most of his life. He was "rediscovered" during the folk music revival of the 1960s and spent much of his later life playing at folk music festivals and recording for Folkways Records.
Document 15: Rocky Top: "Rocky Top" is an American country and bluegrass song written by Felice and Boudleaux Bryant in 1967 and first recorded by the Osborne Brothers later that same year. The song, which is a city-dweller's lamentation over the loss of a simpler and freer existence in the hills of Tennessee, is one of Tennessee's ten official state songs and has been recorded by dozens of artists from multiple musical genres worldwide since its publication. In U.S. college athletics, "Rocky Top" is associated with the Tennessee Volunteers of the University of Tennessee (UT), whose Pride of the Southland Band has played a marching band version of the song at the school's sporting events since the early 1970s.
