U2 and Green Day have had a photo taken doing that old Beatles zebra crossing thing on Abbey Road. They did it when they were in the Abbey Road studios, recording their previously reported collaboration, Skids cover 'The Saints Are Coming.'
U2 photographer was brought in to (kind of )recreate the iconic image - the photograph sees Green Day and U2 walking over the crossing from opposite directions, and apparently shaking hands in the middle. Whether it will be used as a cover on that forthcoming cover version, I don't know. So don't ask me.
