Green/Hendrix meetings

[Norton]

I was re-reading Christopher Hjort’s wonderful Strange Brew, and came across a comment dated Tuesday 13th Dec 1966. It’s a comment from Mitch Mitchell (drummer with Jimi Hendrix Experience):-
Green gave Hendrix a great run for his money. He was one of the few guitarists who wasn’t in awe of him; you know, he didn’t say “Oh God, I’ve seen Hendrix, I’m going to die”

Further on, Thurs Dec 5th 1968 it appears that they jammed together at Steve Pauls Scene Club…. in New York.

This started me wondering how many times had they jammed together,..... and how often was Eric Clapton present….

Just curious
