We planned a really long set at the end of last night's gig and I really had to go. I had planned to ask the piano player to do a ballad real quick while I slipped to the back of the bar and hit the head but at that exact moment he announced that it was someone's birthday and we were all going to sing to her. So I told him to stretch it out and I slung my bass over my back and ran off stage real quick. How about you? What do you do when nature calls while you're playing?
