Don't know if you're talking to me, Sham, but I play it in A. AT a jam, that's what people will probably use, since it works well on the fiddle there. On the banjo, I use G tuning capoed two and drop-thumb frail. When you go down to the G chord on the banjo, try leaving the first string open. I have no idea what this chord is called, but it's a sort of combination G and E7.

As far as verses, they have no end. I could give you a few samples if you are interested.
