Was going through the Rankin/Bass Jackson Five cartoon of the early 70s earlier today when I heard a familiar Harry Bluestone fanfare later released on CPM's archive series, "Award Winner 1". The episode I caught it in was "Cinderjackson", specifically, and it really took me by surprise since they mostly used original music by Maury Laws.
EDIT: Just ID'd "Jazz Fanfare 1", another Bluestone track, as being heard in the same episode.
