Answer 2

A LOT! This is a great show for high schools who want to involve a lot of people in productions. Personally, I prefer casts the size of Godspell or Little Shop, but some high schools want fifty people on stage! Beyond Abner, Daisy, Mammy, Pappy, Earthquake McGoon, General Bullmoose, Apassionada von Climax and a couple of other featured roles, the ensemble cane be expanded or reduced to fit your stage -- 16 or 60
