I dig Stephen Lynch quite a bit. We didn't see Wedding Singer while we were in New York because I had no interest until I heard Lynch was the lead. Hell, guy was up for a Tony. Good for him. Mark Evanier posted this clip which is kind of a mini-mini-making-of docu, and it will give you a taste of the show. From what I can tell, Lynch is probably great...but the show looks terrible.
Hey, I could be wrong. But...I doubt it.
Update: Alas, the video's been taken down.
