Earl does a back up lick that starts around the 9th or 10th fret and runs down on the "D" (4th) string to the 1st fret. Probably lasts 3 or 4 measures. I'm trying to find an example but no luck so far. The Banjo player for the Grascals uses it extensively.
Anyone familiar with it? I'd like to learn it. It's pretty cool.
Thanks.
