Dixieland Droopy

Droopy, a cartoon dog voiced by Bill Thompson, discovers a flea circus called Pee-Wee Runt and his All-Flea Dixieland Band at the circus. Droopy joins the band as their conductor, but must evade the owner after he demands the fleas back. The chase leads to Jazza Plaza, where Droopy outsmarts the agent and becomes famous for playing the Hollywood Bowl as "John Pettybone, Dog of Mystery."
