It's just one cut with Cannonball, the last cut on Side Two, from IIRC, a Paul Chambers Vee Jay side (it's in the Mosaic).
The first two on Side Two are from that great Benny Green Vee Jay album. I mean hey - Gene Ammons, Frank Foster, AND Frank Wess!
(off the record...anybody who doesn't like Gene Ammons has something wrong with them...)
