The title of the episode is a paraphrase of the song "Where is Your Wandering Mother Tonight?" written in 1951 by Red Foley and made famous by The Andrews Sisters. Patti Andrews guest starred on a 1969 episode of "Here's Lucy" where Kim and Lucy stood-in for Maxine and Laverne.
The night this episode was originally broadcast, "Here's Lucy" follow-up on CBS "The New Dick Van Dyke Show" ended its run after three seasons on the air. Like Lucille Ball, Van Dyke had re-invented his original sitcom to create a 'new' version. Both ended within a week of one another leaving CBS without its two most bankable stars.
In her DVD introduction to the episode Lucie Arnaz remembers that the episode was "funny and touching" and "very believable." She says she wouldn't have minded a few more scripts like this one.
In her final bit of physical comedy on "Here's Lucy," Lucy gets stuck in the lotus position while trying to do yoga.
The same evening this episode first aired, ABC broadcast the TV special "Free To Be...You and Me," which was created by and starred Marlo Thomas. Thomas was the daughter of frequent 'Lucy' guest star and Desilu employee Danny Thomas. The show also starred the child of another frequent 'Lucy' guest actor, Alan Alda, son of Robert Alda.
