Very hard to get an audience. So if you're going to fill the theatre, you can't just rely on old stuff.
Every theatre worth anything has somebody in the middle of it who is driving it; like Joan Littlewood with her theatre.
I left my theatre the Loose Moose almost twenty years ago, and I hardly ever go back. Sometimes I go back to do a Mask class. They're doing more of this than I was doing when I left. Often it's the same improvisers but they're older. And now, they don't care if the theatre's full or not.
