I would certainly welcome release of this set on CD - and would buy it. Why not call it a "Cellarful of 67"?

Having them available on digital only is obviously better than not at all but personally I don't buy them in this format.

I wonder what is the purpose of these releases? I know it has something to do with copyright but does it mean that there is nothing left in the vault as unreleased for the years in question? There always seem to be more tracks unearthed all the time so I'm not sure about whether it means that each year becomes exhausted of unreleased tracks.
