Bruce Springsteen played a cameo-filled set at Hard Rock Calling Saturday, but during perhaps the biggest pairing of the evening, "The Boss" was shut down by the management.

Springsteen was onstage in London's Hyde Park with surprise guest Paul McCartney when both musicians had their microphones cut off due to the fact that they had broken the sound curfew.

Springsteen had eclipsed three hours at the point when McCartney joined him for the encore, but before the power was cut, they managed to work in performances of the Beatles' 'I Saw Her Standing There' and 'Twist and Shout' to the delight of the audience. Toward the end of the second song, the microphones faded and comments by Springsteen to the crowd went unheard.

The 29-song set also included guest appearances by Tom Morello on 'Death to My Hometown,' 'Jack of All Trades,' and 'The Ghost of Tom Joad,' while John Fogerty joined in for 'The Promised Land.'

The Daily Mail reports that Springsteen also bowed to the wishes of one lucky fan in the in audience, who had been holding up a banner asking for 'Take 'Em As They Come' and listing the concerts around the world where he had requested it.

After noticing the banner, Springsteen grabbed it and told the audience member, "Tonight, my friend, this is your lucky night. You're going to hear this damn thing. It's a completely obscure track I wrote for 'The River' when I needed some rock songs." Springsteen has reportedly only played the song nine times prior with the last performance coming in Copenhagen in 2003.

As for the "cut off" aftermath, guitarist Steven Van Zandt took to Twitter to discuss his anger over the situation. In a series of tweets, he posted, "The cops got nothing better to do? How about they go catch some criminals instead of f---ing with 80,000 people having a good time. English cops are the only individuals left on earth that wouldn't want to hear one more from Bruce Springsteen and Paul McCartney. I'm sorry, but I have to be honest, I'm pissed! Like I said, it didn't ruin the great night, but when I'm jamming with Paul McCartney, don't bug me."

Hours later, after settling down a bit, Van Zandt returned to Twitter explaining, "Very proud of our association with Hard Rock Calling and Hard Rock in general and what they're doing for rock music. Hard Rock would have let us play all night. There's no grudges to be held. Just feel bad for our great fans. Hard Rock is cool. Live Nation is cool. It's some City Council stupid rule."
