His books treated you like you could be outsmarted by a balogna sandwich ( this is your hand. those things sticking out of your hand are called fingers), but you darned well learned to play. I worked with his mandolin book for a while. I'd probably be pretty good by now if I hadn't needed to sell the mandolin. if I ever get another one I'll be all set. I still have the book. May the Lord take good care of him.
