The Rolling Stones were prevented from finishing their 50th anniversary tour London concert with the signature song “(I can’t get No) Satisfaction” because of a strict curfew. The British rock band was scheduled to complete their acclaimed two-and-a-half-hour gig at the capital’s O2 Arena last night with the 1965 smash hit. But it is understood it was dropped as one of three encore songs because of strict local curfews banning live music from finishing past 11pm. The ageing rockers, in their 60s and 70s, took to the stage for the first time since 2007 as they celebrated 50 years in the industry by performing in front of 20,000 screaming fans Lead singer Sir Mick Jagger, 69, was joined by guitarists Keith Richards, 68, Ronnie Wood, 65, and drummer Charlie Watts, 71. The band had been due to start their concert, the first of their new worldwide “50 and Counting” tour, at 8pm “sharp” but did not appear on stage until just before 8.30pm. About three quarters of the way through the show, Sir Mick jokingly warned his fellow band members they had to “get a move on” with the set as it was Sunday night and a curfew was in place. Fans questioned why the song, considered among the band’s greatest hits, was not played at the concert, which instead finished with another favourite Jumpin’ Jack Flash. Today, some took to social networking sites to express their frustration. One user, Leo Blanchard, wrote on Twitter: “The Rolling Stones dropped Satisfaction from their O2 set because of an 11pm curfew. wow.”
