TA, it was December 1976, and the finale was Maynard and Buddy 'cutting heads'. Each one trying to outdo the other with solos. Usually cutting heads is between two musicians on similar instruments. This duel went on for over 40 minutes, neither one giving an inch, nor gaining one. When they finally stopped, both started laughing, and actually hugged each other, and stood on the stage side-by-side, for their bows. Even the band gave them a standing O, screaming and whistling.
What a night. I'll never forget it, though it was almost 30 years ago.
