Context: Hurshul Clothier (November 18, 1921 – April 2, 2006) was one of the pioneers of the big band sound of western swing.  In 1953 he organized a western swing band, The Oklahoma Travelers, at the time referred to as the youngest band in the West.  Hurshul Clothier and The Oklahoma Travelers traveled the country delighting fans with their unique western swing style and were considered the leading dance band in the southwest.  They provided back up for such country greats as Bob Wills, Glen Campbell and touring with the late Lefty Frizzell . Steel guitar is a type of guitar or the method of playing the instrument.  Developed in Hawaii in the late 19th and early 20th centuries, a steel guitar is usually positioned horizontally; strings are plucked with one hand, while the other hand changes the pitch of one or more strings with the use of a bar or slide called a steel (generally made of metal, but also of glass or other materials).  The earliest use of an electrified steel guitar was first made in the early 1930s by Bob Dunn of Milton Brown and His Brownies, a western swing band from Fort Worth, Texas; the instrument was perfected in the mid to late 1930s by Fort Worth's Leon McAluff, who played for western swing band Bob Wills and His Texas Playboys.  Nashville later picked up the use of the steel guitar in the early days of the late 1940s and early 1950s "Honky Tonk" country & western music with a number of fine steel guitarists backing names like :Hank Williams, Lefty Frizell and Webb Pierce.  The term steel guitar is often mistakenly used to describe any metal body resophonic guitar. James Robert Wills (March 6, 1905 – May 13, 1975) was an American Western swing musician, songwriter, and bandleader.  Considered by music authorities as the co-founder of Western swing, he was universally known as the King of Western Swing (after the death of Spade Cooley who used the moniker "King Of Western Swing" from 1942 to 1969). Billie "Tiny" Moore (May 12, 1920 – December 15, 1987) was a Western swing musician who played the electric mandolin and fiddle with Western swing legend Bob Wills and the Texas Playboys in the 1940s. "Time Changes Everything" is a Western swing standard with words and music written by Tommy Duncan, the long-time vocalist with Bob Wills and the Texas Playboys.  Written as a ballad, the lyrics tell of a failed romance and of the hurt that has healed.  Each verse ends with: Joseph Allen "Joe" Carr (June 22, 1951 – December 14, 2014) was an American country and roots musician, author, and professor originally from Denton, Texas.  Self-taught, he began playing first folk music and later old-time and bluegrass music on guitar at age 13 and mandolin at age 15.  After performing with local Texas bands Roanoke in the 1970s and Country Gazette in the 1970s and 80s, Carr formed a "Bob Wills style" Western swing band, Joe Carr & the Texas Lone Star Band, in 1987.  Beginning in 1984, he taught at the commercial music program at South Plains College in Levelland, Texas, For the last several years of his life, he was in charge of the bluegrass and Western swing departments at the college and was the director of Camp Bluegrass held there annually David Stout "Dave" Stogner (1920–1989) was one of the premier Western swing musicians playing on the West Coast.  Known as the ""West Coast King of Western Swing"", Stogner moved to California to pursue a musical career with the encouragement from fellow Texan, Milton Brown. John England & the Western Swingers is a six piece Nashville, Tennessee band that plays Western swing.  The group has played at Nashville's Robert's Western World every Monday since July 2001.  The Swingers have also performed at New York's Lincoln Center, the Grand Ole Opry, the Legends of Western Swing Festival, the Ernest Tubb Record Shop's "Midnight Jamboree", and has been profiled by Downbeat magazine, the Nashville Tennessean, and other print media. "Faded Love" is a Western swing song written by Bob Wills, his father John Wills, and his brother, Billy Jack Wills.  The tune is considered to be an exemplar of the Western swing fiddle component of American fiddle.  The melody came from an 1856 ballad, Darling Nelly Gray, which John Wills knew as a fiddle tune.  "Faded Love" is a sentimental song about lost love.  The name comes from the refrain that follows each verse: Spade Cooley's Western Swing Song Folio was the first songbook to identify the big Western dance band music as "Western Swing".  In October 1944, ""Billboard" made the following announcement, unceremoniously giving the subgenre its common label for the first time in a national publication: 'Spade Cooley will put out 25 of his original tunes, together with an album of band numbers and suggestions on arrangements for Western Bands.  Book to be titled 'Western Swing'."  All songs in the folio list both Spade Cooley and Smokey Rogers as co-writers.
