Thanks Nicole,
Actually, thought the liner notes talk of it, there is nothing extra on John's addiction. The interviews are extended ones that were in the first release and I don't know how it happened, but not until I played it again did other extended interviews witn Pennebacker, John Stewart and Scott show up.
I was always a little po'ed at how the original tape had that long thing at the end about John, ignoring the success of the 3 other rmembers.
