Found an original live version of this from German TV (dude clearly has the 1000km stare of a man who had to do compulsory military service but was able to obtain good supplies of amfetamine :laugh_at:)

might have been in signals/comint/surveillance (he knows his stuff when it comes to microphones; if you watch carefully you can see (and hear) that he is using a throat mic (for communications radios) for some of the “Ich lieb’ dich nicht du liebst mich nicht aha” parts as well as a popular European news reporters mic for his voice (individual soundprocessing units were not affordable then!)

A more modern throat mic (the one he uses looks like 1970s civillian issue to public services rather than the bulkier WWI era Wermacht ones (and it wouldn’t be a good image to openly use that sort of kit anyway))
