Leroy learned from someone that learned from Uncle Dave, damned if I can recall his name at present but they are both on a wonderful film called Echoes of America made by Mathew Wightman and Leroy was with his tutor at a little place in Tennessee called Defeated!

If you go to you tube an look at all the clips featurning David Holt you will eventually find the guy that taught Leroy showing Dave just how it's done.

If the name comes yo me without having to dig through my shelves I'll post it.
