BTW, I have now listened to all 6 CDs all the way through, and I think it's a really wonderful collection of songs and performers.    A few tracks sound like home recordings or live recordings (with some of the flaws that are common to those, such as extraneous noise from the audience being heard on the track), but even those are quite listenable. Most of the tracks sound quite professional.   And the vocals and instrumentals range from OK (a few tracks) to quite good to absolutely stunning.

I'll post some more specific reviews later, but for now I really think this collection is well worth owning and is a real bargain.
