Goony, litigious songwriter whose song "Minnesota Minnie" has apparently been ripped off by the title song of the 1944 lightweight comedy Kansas City Kitty, supposedly composed by cowboy Jeff Williker. Lee sues and is ready to take over the song's publishing company, Lathim and Clark. Played by an uncredited Matt Willis.
Finally in court, they prove that even though "Kansas City Kitty" was stolen from "Minnesota Minnie," "Minnesota Minnie" is stolen from "Kadabel's (spelling?) Romance Rhapsody," from 140 years ago. There's even a music box with the much plagiarized melody to prove it.
