Talk about a morning wake-up call! The cast of American Idiot proved that nighttime isn't the only time for rock 'n roll as they rose bright and early to perform at Central Park's Rumsfeld Playfield for Good Morning America. Lead by Tony winner John Gallagher Jr., the cast kicked off the concert with an energetic mash-up of two of Idiot's biggest hits, "Boulevard of Broken Dreams" and "Holiday", in front of a crowd of devoted fans who showed up at the crack of dawn. The morning mayhem continued as Rebecca Naomi Jones and her fellow Idiot women sung a rocking version of "Letterbomb" before the guys jumped back in for the show's title song. Take a look!
