Wolgang, I found this at one of the Volkslieder sites (I get them confused) at http://ingeb.org/Lieder/zwischet.html

This URL also provides a MIDI of the tune. The chorus to my ears seems a very close relative of Scottish Soldier.

There was a cross reference to it(somewhere?)as the Bavarian Yodelling Song, but alas I cannot now locate it.

I hope that we can eventually shed some light on this. Regards, John
