American Idiot cast performs on Good Morning America

The cast opened with the chorus of "American Idiot," accompanied by a mixture of choreographed movement and punkish freestyle head-banging, getting the audience excited. They ended with the salute to punk rock, their fists held in the air as the audience screamed.

The audience waited patiently as host Robin Roberts talked about the cast and show, but some of the actors passed the time by doing flips. Finally, lead actor John Gallagher Jr. stepped onto the stage with a guitar, singing the beginning verse of "Boulevard of Broken Dreams," accompanied by violins, and eventually the rest of the cast. Then they transitioned to the faster-paced "Holiday."

After a break, and more praise from George Stephanopoulis, star Rebecca Jones sang "Letterbomb" (with some swear words taken out) while the other female castmembers danced. After Jones called out, "Wake up, America!" the guys arrived onstage and sang the opening verse of "American Idiot."

Guitars in hand, the cast ended their set with "Good Riddance (Time of Your Life)," the song that has ended many a Green Day show.
