The worst kept secret in London over the last few days was that Eric Clapton would join the Rolling Stones on stage at O2 Arena during the band's second anniversary concert.  Given the level of expectation, it's a good thing EC showed up - although his contribution to the evening involved only one song - Champagne & Reefer.  Singer Florence Welch was the other special guest of the band - reprising the role Mary J Blige played as vocalist on Gimme Shelter.  An earlier start allowed for the band to get Satisfaction into the set.  The song got the axe during the previous show's encore in an effort to avoid a stiff curfew violation penalty - one the band ended up getting hit with anyway.  Jagger joked that the previous concert's $160,000 overtime fine had set them back the cost of about 10 seats.
