Ooh, I love Sweeney Todd as well. I'd love to sing in that one, only absolutely no one is brave enough to attempt it -- and probably shouldn't -- in non-professional theaters.
As a native Oklahoman, I've mostly disliked just about everything about that musical, since it has nothing to do with anything I grew up with and makes us all look like a bnnch of hayseeds. Yee-haw ... The title song might be the exception, but as you might imagine, I heard it a good bit growing up.
