Could it be the show didn't have legs without a Green Day member in the cast? And if so, what does that say about the show as legit theater? It says that the show needs celebrities or stunt casting. The grosses for A LITTLE NIGHT MUSIC had humongous drops whenever Catherine Zeta-Jones or Angela Lansbury were out. Are you implying that when they were in it, it was not a musical at all, but just a Hollywood red carpet flooded with paparazzi?
Saying the show can't sell enough tickets without a celebrity is fine, and probably (mostly) accurate, but you said that show became nothing but a Green Day concert just because he was in it, and that's just stupid and offensive to the entire cast.
