Rocker Ronnie Wood thrilled a celebrity-packed crowd when he took to the stage for a surprise performance at a charity gala in London on Wednesday night (20Mar13).

The Rolling Stones star joined blues legend James Cotton and saxophonist MACeo Parker onstage at the U.K. capital's Roundhouse venue for Save the Children's annual A Night of Blues.

Guests including Helena Bonham Carter and her director partner Tim Burton, actress Joely Richardson and model Erin O'Connor, were also treated to performances by KT Tunstall and singer/songwriter Dr. John.

The bash raised more than $1.6 million (£1 million) for the charity through ticket sales and the night's auction, with an original illustration by Burton from his classic movie Edward Scissorhands raising $98,000 (£65,000).
