Bruce Springsteen and Paul McCartney fell victim to a noise curfew.
Rock stars Bruce Springsteen and Sir Paul McCartney were silenced on Saturday night after defying a sound curfew at the Hard Rock Calling event in London's Hyde Park.
Sir Paul had joined Springsteen on stage at the end of the singer's headline slot but both stars found their microphones cut off at 10.30pm before they could address the crowds.
Paul McCartney and Bruce Springsteen were performing at the Hard Rock Calling in Hyde Park in London when they found their microphones cut off before they could address the crowd.
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 had to leave the stage in silence.
The crowd appeared equally bemused. Twitter user @StephenMerchant posted: "Ashamed to be British right now. Springsteen and McCartney playing Twist & Shout in Hyde Park and council pulled the plug cos of curfew."
Springsteen, who played with his E Street Band, had earlier invited Rage Against The Machine's Tom Morello on stage to perform two songs, and singer John Fogerty had joined him for one.
He delighted the crowds with his energetic set, and often left the stage to shake hands with audience members.
At one point he rewarded a fan's loyalty by playing an obscure track from his back collection.The singer spotted a man holding up a banner asking him to play the song "Take 'Em As They Come," and listing the concerts around the world where he had requested it.
Holding up the banner on stage, Springsteen praised the "big investment" the fan had made to see him in places including Madrid and Paris, then said: "Tonight, my friend, this is your lucky night.
