Okay, okay. Perhaps we took a joke too far. But after the viral Facebook success of a photo of a pun-packed TfL poster telling Beatles-hunting tourists that they’re at the wrong Abbey Road, we decided to take action. What action? Why, getting The Bootleg Beatles to turn up in the freezing cold to play an impromptu acoustic mini-gig, of course. All to help out mistaken tourists, if not the poor blokes’ internal body temperatures.
