Laggar Fars Polska ,”Laggar Father’s Polska”, is a common polska from Boda, in Dalarna. It is sometimes called “Laggar Farfars Polska”, also – “Laggar Grandfather’s”.
I learned it in the late 1970’s from Pål Olle, a prominent fiddler from the region at the time.
Here is a YouTube video of a group from Boda playing the tune. They call it “Laggar Farfars Polska”.
