Just found this video by accident. I don’t speak German but can still understand much of what he is saying.
Das ischt eine zemple unt halt!
danke schon, das war sehr gut… 
Yeah that modular is interesting… it’s an RA Moog IIIc with 901s replaced with 921s, dual sequencer expansion option, Bode Frequency Shifter, and TWO Sennheiser vocoders.
I’d be a HAPPY man if I found that system.
I liked the end of that video. Obviously fake, but amusing! 
Yeah that is indeed an awesome IIIc. 
great find! I never heard a Lili Marleen version on a Moog before. Very good inspiration. Heinz Funk mentioned that the operating of a modular synthesizer and a vocoder is very simple (a piece of cake is the (british) phrase of it I guess). The perfect sales man.
