This Essential Jazz Classics reissue has the unedited versions of six tracks but does not iclude the "alternate" of "Things Ain't What They Used To Be" - which in fact is an edited version.
The bonus tracks are from John Lewis Atlantic sessions with Jim Hall.
There are three identical issues of this version on Gambit, Essential Jazz Classics, and Elemental.
Besides the obvious classics, one I only missed by a week or two because he was out of town again when I took a trip to Berlin: Ray Bryant.
John Lewis and the Modern Jazz Quartet.
I have problems with renewal of my Lord subscription. I e-mailed them but they blame it on my bankers. Otherwise I would have taken a look immediately.
