I'm coming in to this a bit late (sorry!) but wanted to comment on the argument that with the age group of the fans and the type of show, formal attire is not necessary for Wedding Singer.
I disagree. No matter what, it's still Broadway and I'm sure serious to those performing 8 times a week. I've rushed Wedding Singer twice (putting me in their target audience, it seems) but I would never dream of dressing up because I think these shows and really any night at the theater should be respected. I don't dress to the nines, but I also don't go in jeans and sneakers. I really think there is a certain decorum for live theater and don't care whether the show is thought-provoking and deep or just light-hearted fun. Everyone associated with the production is working very hard so I think the least we could do is dress appropriately, not be a distraction, enjoy the show and applaud at the correct times, and possibly compliment the cast afterwards at the stage door.
But, that's just me.
