Edelweiss
It is understandable that the song would not have been written in the alternate timeline, as The Sound of Music wouldn't have been written and, being Jewish, Richard Rodgers is unlikely to have survived until 1959 when it was written. However I'm wondering if the song is used as the theme as a metaphor for occupation. That's the way it's used at the end of The Sound of Music, as a subtle protest against the Anschluss of Austria.
