Saw them both at Big Top Chetauqua in northern Wisconsin a couple years ago .Sonny was doing the guitar work in John's band for the whole concert. At the end of the show John let Sonny do a couple of his own tunes. This song was the high point of the show for me.
I’m kind of new to Sonny and I’ve only ever seen him play: A. With a Strat, and. B. Without a slide! Kind of trippy to see his pinky actually bend haha!
