Aidan, Roy was a very special guitarist. I’ve watched lots of his stuff. He was a master of volume (knob) swells plus flirting around the melody taking all kinds of liberties and then coming back to it and nailing it perfectly. IMO he’s in the class of people like Hendrix and other originals.
I’m listening to one of Roy’s renditions of Hey Joe and he’s just morphed into Hendix’s Foxy Lady. Wow-wow-wow.
