On August 17, 1960, five young Britons were approaching the stage of a small night club in Hamburg, about to play music in that city for the first time. To reach the stage, they had come an almost unimaginable distance. From their home, in Liverpool, they had driven in a cream-and-green minibus to the port of Harwich. The bus, teetering under the weight of amplifiers and instruments, had been lifted onto a ferry by a crane. At first, the stevedores had refused to handle such a precarious load; a photograph captured the moment just after they changed their minds, with the sixties hanging in the balance.
