Promoters pulled the plug on Bruce Springsteen and Paul McCartney as the Boss's Hyde Park gig on Saturday night went past its curfew. Steve Van Zandt, one of the guitarists, vented his fury at a "police state" and London's mayor, Boris Johnson, criticised "an excessively efficacious decision", saying the band should have been allowed to "jam in the name of the Lord". But Westminster council insisted the organisers had been responsible for throwing the switch on the finale, which had pushed its curfew too far. McCartney joined Springsteen and the E Street Band to play Beatles classics I Saw Her Standing There and Twist and Shout. Springsteen said he had been waiting for this moment for 50 years. But the show closed to boos and whistles from the audience as the stars appeared ready to launch into another number.
