Which reminds me of the time I saw Jackie and asked him about his old Blue Note recordings and if he was still making money off of them. His rather bitter answer was that he never made any money off of them. He sounded pretty peeved and he wasn't joking. I was very surprised when I saw those latter day Blue Notes after talking to him about it.
Of course, none of this explains that date he did with McCoy Tyner ("It's About Time") for Blue Note. Maybe they paid him enough to make it worth his while?
Other people know this better than I do, but wasn't the practice to pay an advance, which was offset against earnings, and also charge all studio costs, also offset, and perhaps also the fixed fees paid to the other musicians, with the result that there were usually never any net earnings beyond the initial advance?
I thought the leaders got double scale but no royalties for those Blue Notes. Chuck would know for sure.
