Okay, so it's probably more of an Open Jam than an Open Mic, but since I'm still new to that kind of things, I think it's easy to think it's the same...

One question I just thought of: How does it usually work? After you go up on-stage and plug in, and there are others up there with you, do you just play a couple of songs everyone on-stage knows, or do you just stand or walk around up there and jam away until someone gets tired of jamming and leaves and you'll have to jam on without them? Or do you play both songs and random improvised jams?
