I, too, love Willie and enjoyed this video very much. About 5+ years ago I was able to see him in concert at a college nearby. Small auditorium which made the sound great. He is really an incredible performer. They played straight through with just a slight water break. I would go see him again if given the chance.
Trigger is one for the hall of fame but Willie would sound like Willie even on a 3 string cigarbox guitar. His Willieness starts at the tips of his toes and flows to his fingers.
