Stan Freese recorded a fun, and for sure different piece called Play That Country Tuba, Cowboy with the punk rock group The Vandals. His son is the drummer in the band. Its a take-off of Charlie Daniels' Uneasy Rider, where a concert tuba player stumbles into the wrong place and has to quickly gain respect by playing to the crowd. Its available on iTunes as well as Amazon.
