Some good material for sure, love the early 60's stock NYC street / background film, though the split screen format becomes a bit headache inducing after a while.
Best bits to my mind being the Cale commentary, Jonathan Richmans observations and essentially any observation by Mo, Martha , Mary W. and Merrill (Lou's sister).
Quite astonishing, really, that for a combo surrounded by cameras during their prime there is effectively no watchable Cale era concert footage. The Factory rehearsal is priceless, of course, but the paucity of Cale era audio /video is a tragedy of sorts. A significant one...
