I caught Jason & Walter at a blues fest a few years back; they got into a mock head cutting contest at that one too, and I couldn't stop grinning the whole time. The joy they expressed together was powerful. Jason's attitude is infectious anyway. My jaws hurt the next day from grinning so hard. It was that show that convinced me that Walter had turned a corner as a frontman and was really startin' to play the blues,, not just play the guitar.
