Don has been playing in the trombone and/or tuba section of the band for a number of years now. It all started when his data, Steve Dixon, drafted him into indentured servitude for the band's excursion to the Munich Oktoberfest in 1997 (rough duty, eh?... Don had to go to Munich, play in an Oktoberfest band, and drink beer!).
Don fit right in of course -- he is Steve's son afterall -- and has pretty much taken up residence in the band ever since. In fact, the only problem we've noticed since Don joined the band is that the keg seems to run low on beer more often (but that's probably just a coincidence... right?).
