Context: Dorsey Burnette (December 28, 1932 – August 19, 1979) was an American early rockabilly singer.  With his younger brother, Johnny Burnette, and a friend named Paul Burlison, he was a founder member of The Rock and Roll Trio.  He is also the father of country musician and Fleetwood Mac member Billy Burnette. The Rock and Roll Trio were an American rockabilly group formed in Memphis, Tennessee, during the 1950s.  They were also known as "Johnny Burnette and the Rock and Roll Trio" and the "Johnny Burnette Trio".  The members of the Trio were Dorsey Burnette, his younger brother Johnny, and a friend Paul Burlison.  Dorsey and Johnny Burnette were both natives of Memphis, having been born there in 1932 and 1934 respectively.  Paul Burlison was born in Brownsville, Tennessee, in 1929, but moved to Memphis with his family in 1937. Rocky Burnette (born Jonathan Burnette, 12 June 1953) is an American rock and roll singer/musician and the son of rock and roll musician Johnny Burnette.  He is best known for his 1980 hit single "Tired of Toein' the Line" which he co-wrote with Ron Coleman, who formerly wrote, recorded and performed with the Brothers Grim and The Everly Brothers. "You're Sixteen" is a song written by the Sherman Brothers (Robert B. Sherman and Richard M. Sherman).  It was first performed by American rockabilly singer Johnny Burnette, whose version peaked at number eight on the U.S. "Billboard" Hot 100 in December 1960 and number 3 in the U.K. in 1961.  The original 1960 version of "You're Sixteen" by Johnny Burnette is featured prominently on the 1973 motion picture soundtrack of the film "American Graffiti". Johnny Burnette and the Rock 'n Roll Trio is the 1956 debut album of the influential rockabilly band The Rock and Roll Trio, fronted by Johnny Burnette.  Recorded over two separate sessions in 1956, the album includes a number of the band's singles.  2008's "Icons of Rock" calls the album "an all-time rockabilly classic".  Released as a 10" LP in the UK by Vogue/Coral Records in December 1956 (#10041), it was released again in 12" format in its US debut by Coral Records in 1957 (#57080) and in 1978 by Solid Smoke (#8001).  A few years previously, there had also been an unauthorized reissue of the album which featured an exact reproduction of the cover and label, although differences in label and cover formatting noted by collectors reveal it as a reprint.  In 1993, it was released on compact disc by Aris Records (MCD 30489).  1998's "Go Cat Go! : Rockabilly Music and Its Makers" characterizes the CD reissue as "legendary and essential." "Train Kept A-Rollin'" (or "The Train Kept A-Rollin'") is a song first recorded by American jazz and rhythm and blues musician Tiny Bradshaw in 1951.  Originally performed in the style of a jump blues, Bradshaw borrowed lyrics from an earlier song and set them to an upbeat shuffle arrangement that inspired other musicians to perform and record it.  Johnny Burnette and the Rock and Roll Trio made an important contribution in 1956 – they reworked it as a guitar riff-driven song, which features an early use of intentionally distorted guitar in rock music. "Lonesome Tears in My Eyes" is a song written by Johnny Burnette, Dorsey Burnette, Paul Burlison and Al Mortimer.  It was first released by co-writer Johnny Burnette and his Rock 'n' Roll Trio in March 1957. Waitin' in School is a rock and roll song written by Johnny Burnette and Dorsey Burnette.  The song was recorded by Ricky Nelson, and peaked at number 18 in the U.S "Billboard" Hot 100 of 1958.  It is considered one of the best examples of Nelson's contributions to rockabilly.  Joe Maphis provided the lead guitar and solo on this record. The Little Killers were an American rock and roll band who formed in New York City, New York, U.S. in 2001.  They played punky garage rock inspired by the likes of Chuck Berry, the New York Dolls, and Johnny Burnette's Rock & Roll Trio. Paul Burlison (February 4, 1929 – September 27, 2003) was an American pioneer rockabilly guitarist and a founding member of The Rock and Roll Trio.  Burlison was born in Brownsville, Tennessee, where he was exposed to music at an early age.  After a stint in the United States Military, Burlison teamed up with Johnny and Dorsey Burnette to form The Rock and Roll Trio.  The band released several singles, but failed to attain chart success.  Paul is sometimes credited with being the first guitarist to intentionally record with a distorted electric guitar on the 1956 recordings, "Lonesome Train on a Lonesome Track" and "Honey Hush."  The Trio disbanded in the fall of 1957 and Burlison moved back to Tennessee to start a family.  There he started his own electrical subcontracting business which he ran faithfully for twenty years, taking a break when the Trio reunited in the early 1980s.  He released his only solo album in 1997, which received positive reviews.  Burlison remained active in the music scene until his death in 2003.
