Jonas Brothers, Demi Lovato Create New 'Camp' Memories At Tour Kickoff

Saturday's concert in Chicago featured duets, dance-offs and a generous helping of older hits.

TINLEY PARK, Illinois — After Demi Lovato played a raucous set of her original songs, some old-school "Camp Rock" numbers and a few tunes from the September 3 Disney Channel movie "Camp Rock 2," Nick, Joe and Kevin Jonas hit the stage for the inaugural stop of their new tour at the First Midwest Bank Amphitheatre on a steamy Saturday night.

The Jonas Brothers got their half of the party started with "Feeling Alive," "Hold On" and "Year 3000," and girls were immediately screaming, singing and dancing on their seats.

"How are you guys doing tonight? You excited for 'Camp Rock 2'?" Joe asked the crowd before dancers hit the stage for an uptempo, country-tinged new tune from the soundtrack.

The guys played a number of songs off the soundtrack, and when Kevin asked for fans' opinions of the new songs, he received a resounding cheer. The crowd went nuts when Demi came onstage to sing "This Is Me" along with the boys.

Joe and Demi also played their new duet, "Wouldn't Change a Thing."

"You guys are awesome," Demi told everyone before saying good night.

The next part of the night belonged to "L.A. Baby," from their "JONAS L.A." TV show. That led into a cover of the Beatles' "Drive My Car."

After "Paranoid," Joe and Kevin gave their little bro, Nick, the stage for his solo "Who I Am." "Thank you so much for loving me for who I am," he told everyone.

Nick was rejoined by his brothers and took to the piano for "Fly With Me." Then, girls went crazy for the ballad "When You Look Me in the Eyes."

Telling the fans they were going to "take them back in time," the Jonases played "Please Be Mine" as photos of the guys from over the years showed on a screen behind them.

Then the stage was transformed into a swanky jazz club, complete with dancers in '20s garb, for "Lovebug."

For the encore, the brothers brought out their hits "S.O.S." and then "Burnin' Up." And on this sweltering night, it took little to make the crowd burn up themselves, but Nick stripping down to a tank top made the girls scream even more as the show drew to a close.
