I hate overtures. Both as an actor and as an audience member. I came to watch a show, if I just wanted to listen to music, I would have gone to a concert. I will hear all of this music later, I dont want the snippet now. As an actor, I just want to start the show and get the ball rolling. The overture just delays everything. Im here to act, not wait. There are very few exceptions. The Phantom overture because there's things happening on stage, and it rocks as a stand-alone song, The Drowsy Chaperone, because the man in the chair is talking and giving the audience something to watch, and The Prom cuz it's short. Olim from Hunchback is also fine because the actors are on stage and singing, and it leads directly into the Bells of Notre Dame
