Williams gave an extended interview in the 1980 documentary, "The Compleat Beatles", in which he recalled preparing the group for their Hamburg bookings. He reassured Howie Casey, leader of the Seniors who were already established in Hamburg, who had cautioned Allan: "Listen, we've got a good thing going here in Hamburg. But if you send that bum group, the Beatles, you're going to louse it up for all of us." He also recalls auditioning drummer Pete Best, asking him to do a drum roll, which he did "Not too cleverly, but passable."
