Going off at a slight tangent here but if you right handed pickers are fascinated by southpaw pickers try and see Bill Birchfield of the Roane Mountain Hilltoppers. I don't believe he re-strings any of his instruments: autoharp, fiddle, banjo and guitar, and to see him fingering the latter two from over the top and hear the results is amazing. His band is one of the genuine old time(y) dance bands with a long family history.
