When the storm troopers broke into song, singing the ‘Hitlernationale’, residents threw open their windows, misled momentarily by the familiar tune. Realizing quickly that Nazis were trying to appropriate the melody of their revolutionary anthem, the socialist residents countered by singing the refrain from the original text ‘Völker hört die Signale! Auf zum letzten Gefecht’ (‘Comrades, listen to the Signal! Onward, to the final battle!’), while others pelted the storm troopers with bits of debris. Police promptly moved in to prevent serious trouble.
