Billy Butler was a smooth guitarist, and was blessed with Clifford Scott for inspiration. Try playing the sax parts on guitar, and you can feel the beck and call with Billy's rhythm style. Go back and play the guitar parts again. THAT'S what makes the guitar solo so great, in my opinion. Again, keep at it Sir. Good video.
Did you stop to think he is playing it slow to demonstrate and maybe some of us can follow it. Why do we have to be so critical of other players, after all we all have different skill levels. I think he did great.
