Diane Marie Jacobs (born 19 August 1943), known as Dinah Lee, is a New Zealand singer who performed 1960s pop and adult contemporary music. Her debut single from early 1964, "Don't You Know Yockomo?", achieved No. 1 chart success in New Zealand and in the Australian cities of Brisbane and Melbourne. It was followed in September by her cover version of Jackie Wilson's, "Reet Petite", which also reached No. 1 in New Zealand and peaked at No. 6 in Melbourne. The Australian release was a double A-sided single with "Do the Blue Beat". On her early singles she was backed by fellow New Zealanders, Max Merritt & His Meteors. Lee appeared regularly on both New Zealand and Australian TV variety programs, including Johnny O'Keefes Sing, Sing, Sing and Bandstand. She toured supporting Johnny O'Keefe, as well as Ray Columbus & the Invaders and P.J. Proby. According to Australian rock music journalist, Ed Nimmervoll, in the 1960s, "Lee was the most successful female singer in both her New Zealand homeland and Australia ... on stage and on record Dinah had all the adventure and exuberance for the time the boys had".
