Oh hey.. this is nice.. I can't stop myself from adding this link as well. Not sure what year this performance is from but he looks at least 20 years younger.. so possibly late 1980's. It starts off a little rough but it really gets going and then when he plays the main melody properly for the first time, he releases all the tension that he has built to that point... it's really great stuff.
