The flashbacks are taken from the film Strange Bargain (1949). Jeffrey Lynn, Martha Scott and Harry Morgan reprise their roles from the movie.
Because Katherine Emery, who had played Edna Jarvis (wife of the dead man) had died in 1980, Gloria Stuart was recruited to play her in the new footage. Because this was before Titanic (1997) resurrected Stuart's career, she was relegated to a bit role. Mrs Jarvis was senile and features in only one scene at a nursing home (Stuart would have a slightly larger role, and "special guest appearance" billing, 14 years later in La signora in giallo - L'ultimo uomo libero (2001)).
Richard Beymer, who played Sydney Jarvis, was actually 14 years younger than Raymond Roe, who played the same character in the Strange Bargain (1949) footage. Roe had long since retired from acting and was by then a Los Angeles County Sheriff's Deputy.
This was Debbie Zipp's first appearance on the show. Of course, in her later appearances she would play Grady's fiancée/wife Donna.
The title comes from "September Song" composed by Kurt Weill, lyric by Maxwell Anderson for Walter Huston in the 1938 Broadway musical "Knickerbocker Holiday": "And the days dwindle down To a precious few, September, November - And these few precious days I'd spend with you, These golden days I'd spend with you."
