Seems like a nice collection. I have to confess that I haven't been keeping track of what is available for download and what is not.
Most of the tracks here have been covered on the "Classics & Collectibles" set with a few tracks thrown in from the "Black Coffee" anthology. "The Possibility's There" has not been on these two sets, but also appeared on (licensed) Bing Crosby and Peggy Lee CDs.
I guess that still leaves the question about mastering on this new compilation.
