You're a Sweet Little Headache was a song. While in Venice in 1938, Elsa Schneider had a phonograph recording of Benny Goodman's swing jazz recording of this song. After a narrow escape with Indiana Jones, she played the record while ostensibly in the bath, when in fact she used the music to cover her ransacking of her own room.
