Whatever it was I got had the whole Blakey Big Band session, false starts and all. There's a LOT of false starts and incomplete takes. Not at home now, so I can't tell you what version it is. It was Japanese in origin.
Speaking of Bethlehem, there's a version of Johnny Hartman's Songs From The Heart (also from Japan, iirc) with a bunch of "bonus" cuts that consist of what sounds like Hartman either getting lost or forgetting lyrics or some weird shit like that. It's uncomfortable. Those Blakey fuck-ups are uncomfortable. In both cases, the end record was pretty good (and in the case of the Hartman record, very good), but not good enough to document all the hassle that went into getting it there.
Certainly I'm down with full documentation of historic sessions, like with Bird dates, things of that ilk, but things like this are the aural equivalent of watching sausage being made.
