This is an amazing fiddle tune.  The liner notes say that this was Ed's favorite, and it is a real good example of a case where the notation cannot come close to conveying the effect of the live performance.  He plays it blazingly fast, and the overall effect, on me, at least, is almost like being suspended in time.  There is no real melody to speak of, just driving rhythm.  I think the fiddle is tuned to ADAD on this one. This is another of the tunes that he plays without any backup.
