The exterior porch of Steve's childhood home is the same one used as Andy Griffith's Mayberry house. Both shows were filmed at Desilu Studio (until Lucille Ball sold out and it merged with Paramount Studio).
Pamelyn Ferdin, who played Roseann, said on her Facebook page that she was embarrassed about having to throw a tantrum in front of Fred MacMurray.
Mike is mentioned as Steve is entering his childhood home. This is the last time Mike (the oldest son) is mentioned on the show as he has been completely erased from the show, a la Chuck Cunningham on Happy Days.
The song Memories that is heard on the sound track was sung by an uncredited Mike Minor, who had appeared a number of times in bit parts before becoming a regular on Petticoat Junction.
