Green Day fans attending Thursday night's performance of the just-opened Broadway musical "American Idiot" got an extra-special treat following the final bow: The veteran rock trio jumped onstage for a surprise performance.
"This is my first night on Broadway," frontman Billie Joe Armstrong announced as his two bandmates — bassist Mike Dirnt and drummer Tré Cool — took their places behind him. They quickly ripped into a blistering performance of "American Idiot," the first single from the album of the same name that serves as the basis for the musical.
