In honor of this past weekend's world premiere of Green Day's "American Idiot" musical at Berkeley Rep (the show's still technically in previews, and has recently been extended until November -- we'll have a review for you next week), we give you this video of these hometown boys performing the song "American Idiot" live at Abbey Road studios in London. The 2005 concept album by the same name was the band's response to a post-9/11 America, and the rock musical based on the album will most likely move to Broadway after its run in Berkeley. It's directed and co-written by Michael Mayer, who was a collaborator on the Tony Award-winning "Spring Awakening," and it includes a few tunes off Green Day's newer album, 21st Century Breakdown.
