The Rolling Stones will be getting together in London next week -- but not with instruments in their hands. Mick Jagger, Keith Richards, Charlie Watts and Ron Wood will be on hand for the July 12 opening of an exhibition of photographs from the new coffee table book "The Rolling Stones: 50," which publishes that day -- and also marks the 50th anniversary to the day of the group's first show, at London's Marquee Club. The exhibition will be showing at London's Somerset House, and the premiere will mark the first time the four Stones have appeared together publicly in four years. The group is also planning to release a 50th anniversary documentary this fall, but there's no word yet on live performances to celebrate the landmark.
