EmptyFree once wrote about Laibach's "Tanz mit Laibach" from "WAT", mentioning it was heavily derived from D.A.F.'s song "Der Mussolini". Now, I've heard the Deutsch-Amerikanische Freundschaft track for the first time today and must agree with that. In fact, this clears up something about certain lines in "Tanz mit Laibach" which I before that had found surprisingly naive:

"Americano Freunde
und deutscher Kamerad,
wir tanzen gut zusammen
wir tanzen nach Bagdad!"

Now it has become obvious that the first two lines include a reference to D.A.F. and their above-mentioned song; this cuts into the seeming naivety.
Before "Der Mussolini", I'd only known their "Die Kleinen und die Bösen". Basically and as far as I remember, it was drumming, noise and a voice that would buzz or scream (something like "Eating then sleeping then eating sleeping then eating then eating" or "Work is boring! Sex is no fun! Work is Boring! Sex is no fun!", all that in German of course), altogether quite great fun. I think I should deal with some of their later albums as well.
Here's "Der Mussolini".
