When Grandpa gets the organ to start playing a love song to make Marilyn and the bank assistant manager Alan Benson more comfortable, the song is "Let Me Call You Sweetheart" (written in 1910 by Leo Friedman and Beth Slater Whitson). A few moments later when the organ goes haywire, it launches into the trio section of "Under the Double Eagle," an 1893 march written by Austrian Josef Franz Wagner. (The title is a reference to the double eagle in the coat of arms of Austria-Hungary.)
