But which of your song lessons would you rate as best 'general' learning type tunes..........in other words the theory and technique specific to the songs that translates the best to improvosational jamming (my guess is 'Deep river Blues', Killing Floor or 'Rollin. Stone')? I was almost sad when you superior lesson on Buddy Guy ended but now have definitely discovered value into returning often and working hard to get these great tidbits down and ingrained in my guitar brain!! That turn around around the 12th fret alone is worth the price of admission!! Jim C.
