The ex-Beatle says: "I gave Todd the track and my idea and my words, and he turned it into what it is today. Joe's a brother-in-law now - he can't refuse. It needed some of that feeling Joe has. I gave him a call and he came over on a Sunday afternoon."

The session lasted just two hours - but it could have gone on longer if Walsh had had his way. "I tell Joe, when he's done a solo, 'That's it,'" the drummer, singer and producer says. "He wants to do it and do it and do it. That's how he is; but I've known him long enough to say, 'No - we've got it.'"
