I have both, bought from Jazz Record Mart in 1981, during a three week gig in Des Plaines, with a "hotel show band". It was funny, too, you had to order them a week in advance, because it was one of those things where if you didn't reserve it, you wouldn't get it, they were selling with that kind of rapidity.
First saw/heard the a few years before. A college buddy from Houston had them somehow. They were really pricey, around $330/per iirc. Way of range on a student budget, but for somebody who got paid cash weekly, not too big of a sacrifice.
Those records were "legendary" right off the bat, actually, and that was before a lot of people actually heard them!
