The band perform to over 1m fans.Rolling Stones rocked out to over a million fans yesterday on Rio's Copacabana beach in one of the largest concerts ever witnessed.The free concert, which was part of the band's 'Bigger Bang' world tour, saw crowds pack out a 1 mile stretch of Rio's famous seafront, with many more watching from numerious hotels and apartment buildings, while hundreds of boats moored along the waterfront hoping for the best possible view of the colossal stage.For the ageing rockers, the free performance was their first since 1998, and gave the city a chance to put its violent image behind it. "Events like this put the lie to our violent image,'' the city's mayor Cesar Maia said in an e-mail interview with Bloomberg before the concert. "This is an event of international impact that shows the city's specialty for large events and their peaceful nature.''The band performed a two-and-a-half-hour set, which included classic tracks like "Sympathy For The Devil", "Jumpin' Jack Flash" and "Satisfaction". "Rio is Fantastic," Jagger told the crowds in the native Portugese tongue.
