"Happy Reunion" from Newport in '58 with Mex and the rhythm section, maybe a chorus and a half...Lovely...I don't think it is the same take as on the double CD of that concert -- the version which came out on the LP "Jazz Critics Choice" is a tighter performance, very succinct interpretation of the melody, just beautiful.
David Murray talks about Gonzalves in the new Down Beat and says the D&CinB solo was a starting point for his appreciation of Gonzalves as a rhythmic artist, and someone who could place a ton of information in a phrase and have it come out sounding musical. That's a paraphrase.
That long Newport solo is so singable, though, and swinging. Over rated? Well, one could say the whole trip in the 50's was over rated because of Columbia's great promo machine and that it is Duke in the 30's when he was at his height as a composer, and in the 1939-41 period as a bandleader.
But really, you have to dig it all -- taking apart Ellington by decades misses the large picture, the way that certain pieces changed over time or were re-interpreted. Such as "our 1938 vintage,..." you know the rest.
