Known as "The Voice" of "Bob Wills and His Texas Playboys", Rausch was Bob's lead vocalist beginning in 1958. After Wills died in 1975, he continued Bob Willls' legacy recording and touring with the original Texas Playboys. In 2011, the Texas Legislature adopted a resolution designating Western Swing as the official "State Music of Texas". Rausch made a memorable appearance as a band singer in the 1998 Stephen Frears film The Hi-Lo Country, in a scene featuring one of the film's highlights - Don Walder's rendition of I'll Hold You In My Heart." He still performs each year at the bob Wills Day Festival the last weekend of April in turkey, Texas. Leon will be backed by the Jason Roberts Band.
