This was the second attempt to remake a series of one of Neil Simon's plays with African-American actors in the lead roles. The other was Barefoot in the Park (1970).
Demond Wilson purposely shaved his trademark mustache (for the role of Oscar), to distance himself from his known portrayal of Lamont on Sanford and Son (1972).
Demond Wilson stepped away from acting, to become a licensed minister in 1984 (one year after this show's cancellation).
