It doesn't matter. If I were some way involved with an original work and it was being performed illegally ANYWHERE, I would hope that someone would report it. It's the law, and it's there for a reason.
It has nothing to do with the fact that the show is WICKED, it has nothing to do with the fact that the show is being performed my kids.
Whether it was being performed by children or adults, the fact remains that they will be profiting illegally off of someone else's work without paying them a dime. It's outrageous.
I do not take pleasure in other's failures, but by reporting an illegal production, not only would they be fined up the ass, but the director and the students would learn a valueable lesson.
Your argument doesn't make much sense here. If you had any respect for the author and owners of the material, then any theatre enthusiast wouldn't hesitate to pull the plug on an illegal production. It's just stupid to think otherwise.
