I don't speak german at all, but would like to add to Wolfgangs post. There is a Schnitzelbank tradition associated with Basel Fastnacht(Carnival in Basel, Switz.). During the carnival these guys in masks (everyone wears masks) go from pub to pub with a large Sandwich board or easle,on which is drawn funny pictures or diagrams. In the pubs they sing songs or tell stories about current politics or events for the enjoyment of other carnival particapants. These guys are called Schnitzelbanke, which is what drew my attention to this thread. Once again I don't speak german, but have spent a ton of time figuring out menues and signs, this song does not look like Basel Deutch to me, maybe a simalar german dialect from close by.
