If you’re a fan of Disney-manufactured pop acts then you’ll have a soft spot for this partnership between Chevrolet, Disney and the Jonas Brothers, Disney’s male version of Miley Cyrus’ Hannah Montana. Yes, that’s Billy Ray Cyrus’ daughter. Yesterday at Walt Disney Studios, the Jonas Brothers performed in front of 150 LA area students at a “Chevy Rocks the Future” concert. The effort aims to make Chevrolet’s “green” cars cool in the eyes of the bubble gum set. Um, yum?
