It is noteworthy that the NSDAP had no objection whatsoever to that horrid song (unlike the scene in Casablanca). I have heard a recording of volunteers of SS-Charlemagne singing it as they entrained for the east.

Perhaps the line about "impure blood" was particularly agreeable to them.

At the Mass, several French hymns are usually sung. I believe they are specifically "Royalist." If you wish, I will research further.

Just one of the sleazy tricks of that dishonest propaganda-flick-disguised-as-love-story is the shameless theft of the Marseillaise scene, from Jean Renoir's La Grande Illusion.
