I think Georg Kreissler was Austrian Ron, from Wien. I also think there was some connection between him and Tom Lehrer. He certainly did the German version of "Poisoning Pigeons in the Park". He lived in New York for many years and wrote many hilarious songs in English too. He had quite magnificent bad taste in English and German. His English song about a homicidal psychopath is unforgettable and he also wrote a song in appalling taste about two old people dancing a tango in an old people's home. I have probably left it too late to catch one of his gigs, but I wish I hadn't.
