I posted the question about the additional tracks being rejected tracks and this is the reply from Joe Harley on FB:
“Alfred approved and sequenced the original 5 track album. Later, after Alfred had passed, Michael Cuscuna added three great additional tracks to the CD version of the original. Michael was a dear friend of mine and we discussed this reissue before he passed. The additional 6 tracks are very worthy of being released. You can hear one of them now (‘The Take Off’) I did not include takes where there are technical problems like the tape running out or tape starting halfway through. I did not include one take because Michael and I agreed it was not worthy of release.”
I don’t have the US re-issue, just the 1993 TOCJ, which only includes the original five.
