Keith Richards says Rolling Stones members to rehearse later this month

The Rolling Stones' guitarist Keith Richards, in an interview with Rolling Stone magazine, said that he's planning to rehearse in London later this month with bandmates Charlie Watts and Ron Wood, but frontman Mick Jagger so far hasn't said he'll attend.

"We're just going to play a little together," Richards told Rolling Stone. "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."

Richards said the three haven't played together in "three or four years."

There have been rumblings on and off that the Stones will tour in commemoration of their 50th anniversary. Last year at this time, Richards said in an interview that the band planned to record some new material and to tour in 2011, but neither came to pass.

"I just hope we can perform live," Wood said told Rolling Stone. "It'd be great to see if that old spark is there."

The Stones' most recent outing, the two-year "A Bigger Bang" tour, ran from 2005 to 2007 and grossed more than $558 million worldwide, according to figures released to the media by tour producer Michael Cohl. The outing drew nearly 4.7 million fans to 144 shows.

Though there's no new Stones material on the immediate horizon, a reissue of the band's "Some Girls" album is due out on Nov. 20. The set includes 12 previously unreleased tracks, as well as a DVD titled "Some Girls Live in Texas," which was shot in Fort Worth during the summer of 1978.
