The story around that is he was asked to do a solo, he turned up with his guitar and amp, listened to what he was playing over and that was the first take and he went home.
Yes, that is such a wonderful story. It gives me chills every time I listen to it, and when he ends the solo? My goosebumps get goosebumps.
Bach's Tocatta
Yes, that’s it. Sounds glorious on an electric guitar.
