I'm a pretty big Hawes fan, bought Volume 3 of the All Night Sessions, but it didn't excite me, and I never purchased the first 2 volumes. As mentioned above, "Blues of a Sort" is on the OJC CD of Volume 3. I also recall an extended control room conversation (about a football game? don't recall) being strongly audible on that CD.
The Hawes CDs I seem to spin the most are Blues for Bud, Four!, For Real! and Green Leaves of Summer...
