I read somewhere that this was really a Miles album, but they put it out under Cannonball's name to help him fulfil a contractual agreement.
It's possible, Miles always warned musicians about falling prey to labels, but I would be wary of that claim for Somethin' Else. I am pretty sure that Cannonball never had a real contract with Blue Note, this was a one-shot deal between labels. And of course that's not to say that Miles isn't a key influence on the recording either.
