Possibly the recorded version [b]is[/b] Babbitt, doesnt mean that the book is wrong about Jamerson doing lots of takes. Smokey and Norman, Whitfield were such control freaks that hey may have put a Babbitt track on after jamerson did those takes because they didnt like what he did.. He did have a free hand but he did also have a serious temper and the drink didnt help it.
Babbitt said he went to question the residuals he was getting and found contracts for tracks that he knew he had played on, but made out to other people, so I dont think even the players themselves know for certain. The residuals wer paid on the basis of these contracts, many of which were written out after the fact. They were known as "mock contracts"
