Hairspray seems to have been popular recently. Its book is cheesy, but in a campy, fun kind of way. Or, if your community isn't against you guys going a more religious route, Godspell's always a good choice; flexibile cast size, great ensemble roles to show off your talent, a fun structure, and the best part is that it gives the director a lot of creative freedom to play. That show, all in all, is an artist's playground, which is why I love it so much. I'm sure there are more, and I'll post them as I think of them. Hope you find a good show to go with!
