I've noticed that when I play in front of people, I don't think at all about what I'm playing. My hands just go do their thing without any intervention from me. This isn't always good, considering that sometimes my hands don't know a song as well as my head. This doesn't happen when I practice, just when I'm in front of people. Am I crazy? Are my hands posessed? Am I going to have to go through another exorcism? Er, I mean, umm, never mind that last part.
