They created this number for comedian Groucho Marx to sing in the 1939 movie At the Circus. It's a tour de force of comedic writing, in the style of Gilbert and Sullivan. An absolute must-have for men's groups.Other instrumental parts available separately; Recorded accompaniment available separately.
