Back from vacation here's a nice video I found on youtube:
Two nice slängpolskas from the south of Sweden.
The first one is from a sheet music book where a fiddler named Magnus Juringius was collecting and writing down tunes around the 1780s - 1790s. Juringius was from Kalmar, Småland.
The second slängpolska is after a fiddler named Johan Jacob Bruun. He was from Särslöv, Skåne.
