As I am at work, I don't have the CD in hand, but I believe the recording
in question on the DG set was made in 1982.
The recording is very decent on this set, which can be purchased at Tower
Records online for $35 or so. Well worth it I think considering there
are 4-CDs in the set. I myself got lucky and found an unopened set at
a Farmer's Market for only $20.
