We play a hip-hop song and suddenly 25 people on the left jump up and put their hands in the air; then you play Lost Cause and they're like, I don't know about this one.
Most musicians count at the beginning, and never count and talk to their musicians after that. They only talk to them at the end of the song. But I would count with them and talk.
Artists don't always know. Almost every song I ever recorded that was a hit at the majors that the promotional people picked I didn't think it would be a hit. I was wrong every time!
One of them would definitely be the Nelson Mandela gig, when I played the tribute song for him. He was up and dancing, and he really enjoyed it. It was a really lovely occasion.
