Frogman, when I saw Trane in 63, this is about how long he played "MY Favorite Things". They began just like it sounds on the album and they continued after that. Trane went on until he lost McCoy Tyner and Elvin Jones. They decided to stay together and let Trane come back to them. The lady I was with, wanted to know if Trane was on something, but the musician at the table assured us he was clean.
Right now I'm trying to find some music that resembles what Trane was playing, and this is it.

This is "The Olantunji Concert", This is what Trane was playing after he had worked "My Favorite Things" as far as it would logically go. This was recorded in 1967 and it 34:38 long. This is what Trane sounded like when he lost Elvin Jones and Tyner in 63.
I said it once, and I'll say it again, he should have stopped before he got this far out because he was pleasing no one but himself as far as I can see; but I know you being the "alpha musician", scratch that "the consummate musician" can enlighten us farther, and explain how this was the way to go.
Enjoy the music.
