In my younger years,
Have played the keys with my left hand, and had my right arm around the back of some girl, up her top and feeling her tit for a whole song.
Also, got head under the stage once from some chick while the rest of the band was waiting over top of us and yelling at me to hurry up. They were waiting to start the set.
Also, years ago a bar owner (very drunk) came out in front of the band with a shotgun and told us to play some country music. It was chaos as people flocked out the doors.
And the craziest thing....I pee'd in the corner on the stage in the last set - no one could see me but I 'had' to go.
