Sadly, when one of the foremost German folk groups, Zupfgeigenhansel (named after a rather anodyne but famous 19th or early 20th century songbook), split up one of the guys went on to form a band called 'Erich und das Polk' who took pride in finding the rudest and most tasteless songs in the German folk repertoire and presenting them in a way a lot of people found offensive. Strangely enough, it didn't really take off ... (If you can lay your hands on any Zupfgeigenhansel recordings, hold on to them!)
