Who's shown up for a gig to find another band on stage? It's happened to me several times. Fortunately, I've had signed contracts and waited for the other groups to pack up. Once, while playing a real tonk during college days, the owner came up on stage during a song and said, "Boys, I'm gonna have to shut her down. Somebody's ripped out all the plumbing in the men's bathroom." Sure enough, the dance floor was soon flooded and we cleared the place. If you've never gigged in the real fighting, red-neck joints, you've missed something.
