I go to a performing arts school as well and we're always looking for things that people don't expect us to do.
Unfortunately next year looks like 'CATS' Which everyone is loathing because we all hate the show. But our principle wants it >.<
And our entire department is full of boys who'd flip over backwards (literally) to do 'La Cage...' but the girls would throw a fit at not having any parts.
Further more, I just saw a high school do 'Pageant' so I suppose not all boys are uncomfortable in drag *shrugs*
As far as shows that High Schools won't do, I'd agree that most would have a hard time tackling 'The Light in the Piazza' Even though I saw a high school do 'Pirates of Penzance' so it's not like the vocals aren't out there....
I dunno. I think almost anything that's come to Broadway SOME high school would be willing to do.... this is a hard one
because when it's theatre, nothing else matters
