Ulrich Roski--I mentioned him earlier--one of my favorites, as I mentioned, is Des Pudels Kern--about going for a mushroom-gathering walk with his dog--in a military maneuvers area. Apprehended by the military and grilled for names of spies, he gives them all sorts of names of mushrooms.

And George Kreisler--but I can't recall any specific songs.

I also recall Heino--and the Heimatslieder-- of the 70's--not that his music would be one folkies would likely want to advocate. But it sure was catchy.

And Vicki Leandros--not German, but she sang in German--I liked "Theo, wir fahren nach Lodz". Again, not folk, but more pop.

And didn't Mireille Matthieu (sp) also sing auf Deutsch? (as well as French, of course)
