No contest. Jaco Pastorious during a Weather Report show at Convocation Hall at the University of Toronto in 77 or 78. So wasted that he fell over and kept playing a solo flat on his back. Afterward I heard horror stories about the anger within the band backstage over the matter. Jaco still played brilliantly throughout, by the way. Maybe it would have been better if he hadn’t. A beautiful player and a tremendous loss.
