I'm really working on my 3rd position blues and am wondering what some of the best William Clarke songs would be to study. Any juicy 3rd position stuff really. I'm playing Keep on Drinkin by Paul Delay at the moment.
Oh yeah, for diatonic Clarke 3rd position, "Jewels" is the ultimate piece.
With my old blues band circa 2001, I learned Jewels note for note, and we would play it as a set closer - seemed to always get a lively response from the crowd. It's especially cool if you can find a guitar player who will learn all the unison lines to play along with the harp.
