Yup, Paul Gonsalves was Ellington's great rabble rouser. I always think that his solo which took the crowd up to fever pitch is more rock and roll than jazz, but it doesn't matter. The band coming in at the end with the building of chorusses is one of the great moments in jazz. The crowd had to be calmed down afterwards.
It was only recently that re-releases included all of Paul Gonsalves' chorusses, as the original left some out some so as to fit it on an LP (I've not heard the full length). Also he was playing into the wrong mic and it took a lot of post production work by the engineers to bring up the EQ. He still sounds distant because of the crowd noise. But unforgettable stuff!
There was another great solo on a BBC Jazz 625 programme from the '60's, on a number called, I think, The Opener.
