One time...I believe they had the old "Deutchland Uber Alles" song on the movie " the McKensie Break". It was the film about the breakout of german U-boat prisoners in Britain...dont know if its based on real life or not. But listening to almost 500 extras singing that song kinda made my hairs stand up...even sung in german.
Im not praising the song because of its ties to Nazi Germany...But I can see why so many in germany during WWII could be inspired by it. Its powerful.
Dont underestimate the power of inspiration...in any form.
