Leee John was working as a backing singer when he met Ashley Ingram a guitarist/bassist. They formed a songwriting partnership, working in a short-lived band called Fizzz. Together with Ingram and Errol Kennedy they formed Imagination, a three piece soul music band from the United Kingdom in the early 1980s.
Produced by Jolley & Swain their hit "Body Talk" reached number 4 in the UK Singles Chart in May 1981. Their biggest hit, "Just an Illusion", peaked at number two in March 1982. The trio frequently appeared on Top of the Pops and other pop music programmes.
Despite not being an actor, Leee John made a guest appearance on Doctor Who in the story "Enlightenment" in 1983, playing the character 'Mansell'; he replaced actor David Rhule, who had dropped out at short notice due to an industrial strike at the BBC after the rehearsals had begun. The group in the UK waned but they continued to perform, tour and record until the early 1990s. John went back to acting, but in 2003 resurfaced in the reality television show, Reborn in the USA, alongside other singers such as Elkie Brooks and Tony Hadley.
