'Amazing! Incredible! Paul McCartney rules!' Joe Jonas raves to MTV News after the show.

The [artist id="2088128"]Jonas Brothers[/artist] have never been shy about their fandom for all things classic rock. So when Nick and Joe attended the Hard Rock Calling festival in London's Hyde Park, they got the chance to see some musical heroes.

"Amazing! Incredible! Paul McCartney rules!" Joe raved to MTV News after the show. "It was really cool to see how many different age groups there were at the concert. For us, we grew up on Paul McCartney and the Beatles, and it was always on in the house, so I think Paul McCartney is a legend, and Elvis Costello, that will live on for a long, long time."

Nick, who is currently starring as Marius in "Les Misérables" on London's West End, added that seeing McCartney in person only reminded him of other amazing experiences with the musician. "We got to see him at the Hollywood Bowl, and we had the honor of doing something with him at the White House," he said. "But tonight was incredible on another level, and being here in London is just amazing."

The guys even mentioned their top songs for the night. "Obviously, 'Hey Jude' comes first always, but then every time he plays 'Blackbird,' " Nick said.

"I think 'Blackbird' and 'Got to Get You Into My Life' is pretty incredible," Joe added.

The three-day festival boasted headliners Pearl Jam, Stevie Wonder and McCartney, with a mix of rock and pop acts rounding out the bill, including Ben Harper and Relentless7, the Gaslight Anthem, Jamiroquai and Corinne Bailey Rae.
