*raises hand* I really, really love musical theatre too
I'm too tone deaf so I've never been in any production besides a cheesy one in 5th grade that everyone had to do :p
But I like watching them. I've seen Cats, Les Mis(my favorite!), and Into the Woods live. I also like this German musical called Tanz der Vampire, The Book of Morman, Sweeney Todd, Rent, and a few misc. others.
