Apparently Mercury Records recorded this entire concert to issue shortly after, but never got around to it. And when they did, only released two tracks from the concert.
This weekend you get to get to hear what they left out. The announcer mikes apparently weren’t going through the band mixer, so the announcements are distant and the band is quite up-front, as you quickly find out when they start.
Here is that memorable concert from the 1962 Newport Jazz Festival featuring The Rahsaan Roland Kirk Quartet.
