It's Only Make Believe by Conway Twitty, Hoots Mon! by Lord Rockingham's XI and Tom Dooley by the Kingston Trio were all UK chart entries in late 1958. The Chipmunks Song was a novelty record of the same period 'sung' by an animated music group billed as Alvin and the Chipmunks (sometimes, simply The Chipmunks).
