LONDON — Bruce Springsteen and Sir Paul McCartney were silenced after defying the sound curfew at Hard Rock Calling. McCartney had joined Springsteen, known as The Boss, on stage at the end of the singer's headline slot in London's Hyde Park, but both stars found their microphones cut off before they could address the crowds. Springsteen, known for his long performances, had been playing for more than three hours and had exceeded the curfew by half an hour. After belting out hits such as Born In The USA and Because The Night, he welcomed Sir Paul to the stage to sing Beatles hits I Saw Her Standing There and Twist and Shout, but neither performer had the chance to thank the crowd, and they had to leave the stage in silence. — Agencies
