I'm trying to find out some background to a nice 3-part 6/8 tune that I picked up from a hurdy gurdy player named Heloise in Canberra (Australia) around 1988. It may be misnamed, as "Burgerbeitz Tanze" doesn't seem correct German to me. Does anyone recognise the tune and know its origins?

I've recorded it here in the key of D and the abc version for the tune as originally played in the key of C major is below:

X:1
T: Burgerbeitz Tanze
K:C
M: 6/8
L: 1/8
