I'd be interested to hear the response to this question as the concert (along with the other concerts, LA Forum on the 18th, 19th and San Diego on the 20th) we professionally recorded by Cream's management for official release. As it turned out, only 3 tracks were officially released from the Oakland performance (the rest were too badly performed) and 3 from LA Forum concert on the 19th (don't know why the rest from these later concerts weren't released).

What the Vault seem to be playing are the official releases as well as other tracks for the Oakland concert from a well known bootleg which appears to be have been made off the original professional recordings.

I don't think these are recordings made by the late, great Bill Graham but I'd appreciate more information on these and any other recordings the Vault have of this fanstistic band as it's severely under-represented on the live recordings front.
