maybe my ears are deceiving me ,but lunsford sounds as if he is picking with index finger and hopping over to the first string with his index,sometimes instead of using the strum,similiar to round creek,but with the left hand pull off omitted,so as well as using bum ditty,he did a melody and ditty that didint involve a brush but used an upward single first string pluck and then a fifth string pluck,is that right?
