O-10, since this was a "bruha" that you started (no problem there), don't you think that what YOUR opinion of what the answer is should be stated; at least once? I am genuinely curious and with no ulterior motive. Btw, I don't think that everyone who knows for sure is dead. Still hoping to hear from Cuscuna and there might be others. After all the bruha, I would like to know for sure myself; although I'm pretty sure. Doesn't mean we have to keep talking about it though or with rancor. My two cents.
Btw, re the importance of contracts in the music busines, on the Coltrane "Ole" recording that I posted, Eric Dolphy appears, for contractual reasons, under a pseudonym.
