Richards says Mick Jagger the 'Mum' of the Stones

Keith Richards says if the Rolling Stones were a mom-and-pop operation, Mick Jagger would be the "Mum."

"Mick has to get up in the morning with a plan," Richards tells Newsweek magazine in its latest issue. "Who he's going to call, what he's going to eat, where he's going to go. Me, I wake up, praise the Lord, then make sure all the phones are turned off. If we were a mum-and-pop operation, then he'd be Mum."

The Stones' new tour kicks off Aug. 21 in Boston. Their latest album, "A Bigger Bang," is due for release next month.

"I could see why some people may think we're phoning it in after all this time," the 61-year-old Richards says. "But playing the music we do, and playing it with these guys, 'Jumpin' Jack Flash' can be a new song to me every night."

"I mean, we don't need to do it to feed our families," he says. "We don't need to do it to prove anything."
