Myers' songwriting career dated back to the 1940s, and his DeKnight moniker appears on several country and western recordings made by Haley in the 1949-51 era. He co-wrote with Tom Gindhart and copyrighted the song "Ten Gallon Stetson (With a Hole in the Crown)" in 1948, a song which Bill Haley recorded on Keystone Records and released in 1950. "Ten Gallon Stetson" was the first release by Bill Haley and the Saddlemen, a group which would evolve into Bill Haley with Haley's Comets and Bill Haley and His Comets.
