Three of the four members of The Rolling Stones will meet for a jam session in a London studio later this month, according to an interview in Rolling Stone. According to Richards, “We’re just going to play a little together, because we haven’t played for three or four years. 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.” The four members of the Stones were recently spotted coming out of a London office after a meeting. The Rolling Stones are rumored in tour in 2012 as part of their 50th anniversary celebration, though no formal plans have been announced.
