Yeah, I've got a vinyl copy, but I'd bet that if they put it out on CD they might manage to dig up some extra unreleased material from the gig. Wouldn't that be nice? Woody in top form.
One of the "extras" not included on "Stepping Stones" appeared on one of his Columbia studio albums ("United" I think). Unfortunately it did not appear on the studio only Mosaic.
The track is titled "Escape Velocity" and sounds quite a bit like "Impressions". Off the top of my head, I think it was written by "Larry Willis, Woody's pianist at the time. Any CD issue should at least include this.
