It's believing you can push through the exhaustion just to be able to sing after you do a cartwheel or a split.
I have been a big guy all my life, I am not going to lose a bunch of weight, because then you're like that weird fat person that got skinny but still has a big head. I don't want to do that. So I'm just trying.
In no instance is there to be a musical or opera of Inherit the Wind because it doesn't sing. It's an intellectual play.
