I mostly run on autopilot these days, but when I mess up, sometimes it's epic. Ever drive the wrong way on a one-way street, and wonder why all the cars are parked in the wrong direction? We play "White Rabbit," which has a long drum/bass intro. I started it in the wrong key, sure that I was right. At first one of the guitarists just gave me stink-eye, then the other guitarist mouthed to me from the far end of the stage "Wrong key!" and I still didn't get it. Finally the first guitarist got in my face and said "F#!" and finally, finally I got the message. Now: Because the intro is just drum and bass, getting the key right was no big deal. The big deal for me was being so sure I was right when I was totally wrong.
