Thanks Quasimado, that's odd about Pepper because he played with him during Pepper's later years, on the "Hollywood All-Stars" sessions.
I always felt 50's Pepper was almost like a Tristano-ite, in the way he approached a few standards he returned too, like "I Can't Believe You're In Love With Me", he does 3 versions that I know of, one with Marsh, the approach is different on all of them, and on the last one on "Intensity" which is my favorite, he is very Marsh like, IMHO.
