Here's Doc's version of Matty Groves:

Doc was an excellent fingerpicker. If you listen to Matty Groves you'll find it amazing that he used his thumb and just his index finger- like Merle Travis.

Doc named his son, Merle for Merle Travis, just as Chet named his daughter Merle for Merle Travis.

Not many people know Doc was also a good banjo picker, he played three-finger mountain style like Charlie Poole and Doc Boggs. One time I was back-stage, no one was there, and Doc played Country Blues for me on the banjo- I'm sure Doc Boggs would have been proud.
