Do you remember that scene in Rent where Mimi comes out and sings "Where has it been writ, my life should come to sh*t"...? ( I don't either.)
The point I've been making isn't that Broadway shows can never be successful if they include swear words. There's such a thing as artistry and characterization.
Have you seen "The Pirate Queen"? If so, do you think there's anything in the show's book or lyrics that is any way remotely comparable to the shows you listed?
