Thanks guys. That actually makes a lot of sense! The mic delay. It is just a little strange that it happens every time in THAT scene. Saw it 4 times and Emma was sick during all, but getting better.
Three things that MOST DEFINITELY sound recorded are Dr. Dillimands goat noise, Elphaba's witch laugh, & Nessa's "it was Elphabaaaaaaaaaaaaaa". And I've seen this show millions of times. I'm telling you, it's just this tour, right now.
