Plenty of other German language songs in the Legion. Many dating back to the 1800’s.So long as they don't move on to 'SS Machiert in Feindesland', or if they do, stick to the FFL version sung in French.
Before anyone starts off again with the fallacy that the Legion was full of former SS after WW2.
p.s. “Devil’s Guard” is sensationalist fiction written by an American hack; before anyone starts quoting that.
