Loosely based on a popular German marching song called Zeit Marsch, or Sang der Gesänge, composed by Hanns Eisler, and written by Wladimir Majakowski with the lead vocalist Ernst Busch.
Although, it can be debated whether is it really German, because it's obviously a communist song, and the communists were known internationalists. Anyway, it caught my ear, and when it happens, it's not a good thing for the song - because at some point, eventually, the urge can overwhelm me to mutilate it and try to assemble a wholly new creature...
