A guitarist sat tuning his instrument all through the first set that the band played. Each time the leader pointed to him to take a chorus, he would say, "No, man, I'm still tuning up." Half an hour into the gig he was still not ready.
"Why do you need so much time for tuning?" asked the leader. "When I went to hear Segovia he played a whole concert and I didn't see him tune up once!"
The guitar player gave a shrug. "Some cats just don't give a damn!"
