The title of this episode comes from the foxtrot song of that same title, music by Richard A. Whiting and lyrics by Ray Egan. It was composed in 1921 and became iconic for the decade of the so-called roaring '20s.
This is the first of three appearances Phyllis Coates makes in the series, each time playing a different character. She is perhaps best remembered as the original Lois Lane in the 1950s TV series Adventures of Superman (1952).
