Rok, I can hear one of my childhood friends laughing 0n that record; he must have painted a mustache and wore a big hat to get in the Pershing because he definitely wasn't old enough. I would know that "donkey" laugh of his anywhere. I don't know exactly where on the record this appears, but listen for an unmistakable "donkey" laugh and you'll know that's him.
You most certainly would not have minded getting kidnapped by "Legba's" lady who "Tubs" tried to rescue, she was incredibly beautiful; look it up on "you tube".
I never heard of "George Russel", but I will see what I can find by him; what I found by him on "you tube" sure sounded good. From what I read, that you pointed out, he was most certainly what you would call a musical genius in the academic sense.
Enjoy the music.
