There's also a grey area set (3 or 4 CDs… I forget already!) of the last nights at the Fillmore 1971, under the artist Albert King's name but it also includes several other artists including the BBs' set which was recently released as a single CD. I'd quite like to know whether that might also be a different recording, as I think it's on a different label.
Apologies for going slightly OT but while we're talking grey area CDs…
Double disc set from an Eagles 1976 radio broadcast also due. Now, there's NO WAY Henley would allow that to happen...
