The season 4 finale The Family Man (1975), served as the backdoor pilot for this series. Other than the first scene which took place in the Sanford home, the episode took place in a different house and had no other cast members from the show other than Whitman Mayo.
This was the first of three Sanford and Son (1972) spin-off/sequel series, followed by Sanford Arms (1977) and Sanford (1980). Only Sanford (1980) made it to a second season and none of them lasted longer than 30 episodes.
