Boo, I guess for a jazz aficionado Rory's rendition was fantastic. However, if I were to play that song the same way, using a guitar or an arranger keyboard, my audiences would toss me out on my ear. It's as if Rory was trying to hit as many notes as possible in the shortest period of time. That said, his dexterity is beyond belief. I've never seen hands move that fast and accurately in my life. It's a rare talent to be sure.
All the best,
