I hate it when I feel so dumb. What is the question again? Are we supposed to be talking about musicals that have an exclamation point in their title? If so, why are we talking about Wicked? Or is that the point Best12Bars was trying to make?
I had a close friend who wrote book and lyrics for a rock version of The Picture of Dorian Gray. It was terrible but I was kind. He never found anyone interested in setting it.
