German Polka

I'm doing a project at school in German class at school, and one of the parts of it that I'm doing is learning a polka...

...On the Banjo.

So if there's anyone out there that's transcribed a tab for banjo from an actual German Polka
(not Irish Polkas) then I would be grateful, along with any advice someone can give about playing polkas on the banjo. I you happen to have it transcribed on 3-finger, then that's fine, but Clawhammer would be better.

Thanks
