Originally billed as England's answer to Elvis Presley, Cliff Richard managed to stat on the UK charts for decade after decade. But it wasn't until 1976 that he made his first serious foray into the US charts. "Devil Woman", written by Terry Britten and Christine Holmes, was released in May of 1976 and peaked for three weeks at #6 in October of 1976. In the UK, it topped out at #9.
Richard was reluctant to record the song because of its subject matter. He would later tell the story of an Australian fan who had become interested in witchcraft until this song convinced her to convert to Christianity.
What isn't clear is whether Cliff Richard recorded the song before its co-author who sang ( flatly but with exuberance) under the pseudonym Kristine Sparkle.
