The Foo Fighters frontman, who duetted with Jagger on the 'Sticky Fingers' track 'Bitch', is the latest guest to crop up at the Stones' '50 and Counting' gigs. Tom Waits and John Meyer have also appeared, as has Katy Perry, who got onstage with the band in Las Vegas for a duet of 'Beast Of Burden'. Last week, The Rolling Stones' former bassist Bill Wyman has said he will "never" play live with the band again. Wyman, who played with the The Rolling Stones between 1962 until 1993, joined the band onstage for their 50th anniversary gigs at London's O2 Arena last November (2012), but in April he said that he would not be interested in rejoining the group on a permanent basis because he has "better things to do". In an interview last week, he seemingly ruled out the possibility of performing with his former bandmates ever again. "The nice thing was that my kids saw me on stage with the Stones," he said. "I've always maintained that you can't go back to things, and they can never be the same. It's like a school reunion, or Tony Hancock's Army reunion. If you try to go back and have a relationship with someone, it doesn't work, and it's the same musically. It doesn't work. It was a one-off. Five minutes. OK, never again. No regrets, we're still great friends."NME
