Extract from the Solomon King website
In 1974 King recorded the title song for the feeble film The Doll Squad, starring Francine York, which is now seen as a prototype for Charlie's Angels. He had recorded a gospel song, "This Beautiful Day", under a different pseudonym, Levi Jackson, and, although the single sank without trace in 1971, it was reactivated in 1978 and became popular on the Northern Soul circuit.
