It's a Murphy bed that pulls down from the "wall". They could probably do the show without the bed, but who knows...maybe it won't go up and is blocking part of the stage. That WOULD be a problem.
So, that was the Drowsy Chaperone. Oh, I love it so much. I know it's not a perfect show...but it does what a musical is supposed to do. It takes you to another world, and it gives you a little tune to carry with you in your head for when you're feeling blue. Ya know?
