The Piano Man is not quite ready to give up touring. Billy Joel has said his current tour will be his last big-budget concert jaunt. But that doesn't mean he's never going to hit the road again. "I'm not saying I'll never play again. I'm just not going to tour like I've been touring," Joel said this week, after being inducted into the Rock and Roll Hall of Fame. Joel, who has been dabbling in classical music in recent months, said he simply got tired of motels and lying in unfamiliar beds, staring at "cottage-cheese ceilings." "I got homesick," he said.
