Regardless of whether the music is 'releasable' or not, something that is never discussed is the actual compositions that are on the Shorter date. The BN discography gives only sketchy titles. It is not clear if these are written pieces or were improvised on the spot. Curiously, even people who have heard the session cannot seem to answer this question! I asked Mouzon - he didn't remember the date, but said that Wayne always brought music to the sessions. I tried to find out from Wayne when I put together the appendix to the bio, but I was not able to reach any definite conclusions in the short time-frame we had.
So, in addition to thinking of this as a 'lost' Shorter session, I also think of this as the five 'lost' Shorter compositions.
