Here's one for you: the classic Fred Astaire & Ginger Rogers movie "The
Story of Vernon & Irene Castle."  Early on in the movie, Fred (Vernon) is
invited to Ginger's (Irene) house, where she tries to impress him by
performing a goofy song & dance number, dressed in a clown suit, and
accompanied by Walter Brennan pumping a player piano!
