Green Day brought their allegedly political punk rock onto Good Morning America this morning, playing snippets of older songs, but busting out the full versions of current single, "Know Your Enemy" (above) and "American Idiot" (below). I haven't watched Good Morning America since I was in high school and we had to watch it for current events, but I can't remember there being a bigger crowd for a performance on the show.

Green Day's 21st Century Breakdown is out now.
