"Keith Richards is a man without regret. When I ask him if--given the chance to do it all over again--he'd start taking heroin, he doesn't pause. "Oh yes. Yes. There was a lot of experience in there--you meet a lot of weird people, different takes on life that you're not going to find if you don't go there. I loved a good high. And if you stay up, you get the songs that everyone else misses, because they're asleep. There's songs zooming around everywhere. There's songs zooming through here right now, in the air."
