“If I didn’t think it would work, I would be the first to say, ‘Forget it.’ But we’re fighting people’s misconceptions about what rock & roll is supposed to be. You’re supposed to do it when you’re twenty, twenty-five—as if you’re a tennis player and you have three hip surgeries and you’re done. We play rock & roll because it’s what turned us on. Muddy Waters and Howlin’ Wolf—the idea of retiring was ludicrous to them. You keep going—and why not?”
