A few years ago we lost all electricity at the club, with a room full of people. I did two hours with acoustic guitar and vocals and only the few hundred songs in my head! The kitchen cooks with gas and they used candles at the tables. Turned out to be a special night for all of us!
For those that want to use binders. I have a dozen or so for sale in a box in the attic, along with a bunch of fake books. Probably stuff you can't get anywhere else.
Also will trade them for food. Or more mics. Or sex. Oh, never mind. I had a proposition just last week. I told her okay we'll get a motel room and if I can do anything I'll pay my half.
