Good Morning America Summer Concert Series: Jonas Brothers and Demi Lovato

After kicking off GMA's free concert series in late May, the JoBros and Demi Lovato return for another early-morning show. The Disney superstars will perform songs for their upcoming TV movie, Camp Rock 2 (premiering Sept 3), a sequel to the wildly successful original. Though the park doesn't officially open until 6am (the concert starts at 7am), we suspect many fans will start lining up earlier.
