40 Years

[Norton]

I have a double Live at the BBC album which is a compilation of tracks released in 1995. (this is not the Live BBC from the Paris Cinema, April 9th 1970 ). See the following comments from:-

Quote:-

"Contains live material recorded for the British Broadcasting Company between 1967 & 1970

On the whole, less improvisational than some may hope but still colorful and varied nonetheless. According to "The complete recording sessions" book, there's at least another 70 odd recordings still in the BBC vaultsof the Mac up until 1971, one can only hope these see the light of day soon too."

My question is:-

Does anyone know on what albums (if any) the 70 odd tracks surfaced over the last 15 years?
