It's the latest episode in Bono's sprawling "Finding Douchey Ways to Pay Tribute to Musicians I Admire" project. You'd think two well-travelled bands would have the tact not to block traffic in front of London's Abbey Road Studios, but that's just what a couple of videophone-toting business travelers saw U2 and Green Day doing earlier this week. As the chatty Yanks headed out to the famous studio to photograph themselves on the equally famous crosswalk outside, they discovered all seven members of the two bands (who are at the studio recording a cover of The Skids' "The Saints Are Coming," to be debuted at the reopening of New Orleans' Louisiana Superdome) strutting out to do the same. It's all explained in the YouTube video, which includes more footage of the tourists explaining the experience on their cell phones than of the actual famous people. And, as though Bono wasn't already doing enough ass-kissing for everyone on the block, one of the Americans gives us an "I'm a grown man but I simply must get my picture taken with Billy Joe Armstrong" moment.
