Fred ~~~ There is a rather nice sounding tune called "GILSAW" that a friend of mine worked out for clawhammer style banjo. It's not one of the more simple tunes, however its worth the effort once you get it worked out. You can find it at:

you have to scroll down through the fiddle tablature to get to the banjo section.

Have fun~~~~~
