He really seems to enjoy listening to it and watching Jerry Scheff play:
As you would expect from someone like the King who wasn't a bassist himself but still had a Gibson EB doubleneck 4-string bass/6-string-bass custom-made for himself. Though I would imagine that the 6-string was probably tuned as a baritone guitar.
I like the gusto in Scheff's playing - that solo isn't perfect and has rhythmic inaccuracies, but it lives.
His son's Jason (the Peter Cetera successor in Chicago) homage to his dad Jerry ...
Kind of how you like to be remembered by your kids, isn't it?
