I've always had odd taste in music, and I've been drawn to folk music for a long time. I particularly like Bela Fleck's version of the Clarinet Polka as performed on a banjo.
And branching from that, there's always the classic Flatt & Scruggs tune, Polka on a Banjo.
Going back more to the era of Whoopee John, there's Mississippi John Hurt and his blues recordings.
But that song is a bit too dark, so let's round this off with a blues instrumental from the same era.
I don't know of any folk music tradition in my family, although the Mother Thing studied music in college, and part of my ancestry family is as Germanic as Germans can be, while others were a mish-mash of western European and British Isles stock.
