Thanks again. I was aware of the background of the Yiddish and I had already tracked down the music on the net, although it would have been easy enough to lift it from the Zupfgeigerhansel album. The meaning of the lyrics is simple enough for anyone with a smattering of German (which I have). I also have the good fortune that my girlfriend speaks Russian, which usually fills in most of the gaps. What is interesting, is that you have given me a clue as to its origin. That context of it being against a background of mass migration is particularly poignant. I really hope other posters appear to shed more light on it.
