My first attempt at working out a tab... It's (hopefully) something like the intro to "Nine Pound Hammer" as played by The Stanley Brothers at the Chicago Folk Festival in 1961.. I found a couple of errors in it this morning - so have redone it & deleted the original post...

Also After thinking about it, the intro is only about 18 seconds long and over 50 years old... so shouldn't run against the BHO rules?

Send me a PM if you want to hear the full song it (it's on the Stanleytone STCD 5003 "Folk Festival" 2CD set).
