If you haven't taken a tour of the Met, you should, it really is a pretty spectacular space. They've got the stage, and then a full sized stage behind and to either side of it. As tea lady pointed out I even think there's one below it. It's perfect lighting-wise. It's perfectly set up to broadcast. Honestly, this would have been pretty awesome I think.
The space was designed to run things in rep, so I think it's a shame this didn't happen. Back to radio city. Bummer.
