Alan, that’s one I’ve played a lot since I do some Rock and Roll Legends shows which include a Holly Tribute artist.
Unfortunately I just learned the King Curtis original sax part but never wrote it down.
It’s pretty easy. Have you sat down and tried it out yet?
The good news it’s in concert Bb so C on tenor and you can either copy his licks or make up your own because all you need is the C major scale, with an emphasis on the major 7 note (which is the B)
Yes all those fills and solo licks consist of only notes in the C major scale.
