As I wrote before:
"I don't hear "lost", it's not like he's in a different place in the tune or the timestream (beat ahead or behind). (Ed Fuqua)

He's not lost. " (Gerry Grable)
Listening for intention(which is always best) doesn't mean you're not supposed to recognize mistakes being made. As long as the "mistakes" don't interfere with the intention they don't really matter, agreed. But in this thread the question of "what happened here" came up. I listened and found out. That's all.
And as I wrote before, being outside of the form doesn't always equal lost or that he doesn't know where he is in the form.
I think if it were more straight ahead musicians it would be more clear, but like I have already said, what he does here is less "out" than what Coltrane did with "My Favorite Things".
None of us really know - my argument is based on how people in that scene were playing then, to my ears it sounds less extreme than Ornette, but right in line with what Paul Bley and others were doing at that time.
He could have been lost, or he could have been trying to push things out and Warren wouldn't go with him so he came back.
He could have just heard that line, played it and came back it.
It is great to be able to keep forms solidly, but not being able to hear music past the song form being "the law" is what is disturbing in the thread.
I hear him stop supporting the harmony, but I also hear a beautiful, strong line that, to me, is more important than "All the Things you Are".
