Herbie Hancock lost session

[Hardbopjazz]

I am wondering what went wrong with this session that it never made it? The one track that did make it sure sounds like it was ahead of its time. It was more of an R&B sound.

I thought that one track on the Lost Sessions CD ("Don't Even Go There"(?!), surely named long after the fact) was kinda stiff and awkward, but no more so than a lot of jazz-funk. The 'lost session' I'm dying to hear is the Bobby Hutcherson R&B covers session from '70/71(?); again one (or two?) cuts have emerged on sampler(s) ("Family Affair" & ?). [Do I get a prize for gratuitous overuse of {parens}?]
