When does My Three Sons return?

My Three Sons chronicles the life of widower and aeronautical engineer Steven Douglas as he raises his three sons. The series originally featured William Frawley (who had first co-starred with Fred MacMurray 25 years earlier in the film Car 99) as the boys' maternal grandfather and live-in housekeeper, William Michael Francis "Bub" O'Casey. The first season, consisting of 36 episodes, was directed in its entirety by Peter Tewksbury, the Emmy-winning director of Father Knows Best. The address of the fictional home in Bryant Park was 837 Mill Street.
