 Danny Kayes wife, Sylvia Fine, wrote the lyrics to a song in which  Walter Mitty fantasizes that he is a misogynist womens hat  designer. She was a musical theatre buff, and introduced a reference  to the song "Ol Man River" (from "Show Boat") into the lyrics of  "Anatole of Paris", as well as satirical references to "Show Boat"  in one of Mittys daydreams.
