Wayne Skertich, whose house is near Yellowstone and the site of Bill and Allan's first night in Montana during the Mudcat Adventure, has a family background of the Skertich Brothers Tamboritza orchestra. Wayne has a tambura (large bass like instrument) in his living room. Tamburaweb is a site that I linked to earlier to show the Skertich Brothers orchestra. Tamburaweb has a large collection of songs and information about southeast European music.
Here is the site: Folk Songs and Singing from Southeastern Europe
