Keith Richards has been the most vocal about it, from Rolling Stone Magazine: Keith Richards will meet fellow Rolling Stones Ronnie Wood and Charlie Watts in a London studio. "We're just going to play a little together, because we haven't played for three or four years," Richards says. "You don't necessarily want to rehearse or write anything – you just want to touch bases. That's a good start: me, Charlie and Ronnie. Mick's welcome, and I'm sure he'll turn up, but right now we just want to get our chops down."
OK, cool. But another string floating around is cooler - Richards has also invited Mick Taylor and Bill Wyman to consider getting ready for something.
He told Spinner in an interview: And of course everyone else is welcome. Mick Taylor's welcome. I don't see why everybody who was a Stone shouldn't be involved. I read somewhere else that Bill Wyman is at the ready for whatever transpires (can't find where I read it though!) Interesting since he gave up the band due to a loathing of touring.
Meanwhile, the Stones just re-issued Some Girls with 13 bonus/cleaned up tracks from the 1978 sessions, a-la the Exile on Main Street reissue. The band also put out a live concert film from the 1978 tour, called Live in Texas. I have the CD, and the concert DVD is in the mail - watch reviews soon. And while I think the Stones jumped the shark long ago, I'd be up for a concert with Mick Taylor, just to see him work with these guys again.
