I don't know if I trust any comments left on You Tube. Most seem to border on the psychotic. But as I was looking for footage of The Who from 12/31/68, I stumbled upon this. Within seconds, you will notice that it is a kuh-RAZEE mix, like John Entwistle broke into the studio one night after a few pints, got hold of the mixing board and said "Oh yeah, Pete? I'm too loud, you say? Well, how's this?!"
One comment references a single from which this mix originated. I have said single and while it's sounds pretty damn Ox-heavy, it's nothing like this video. It could have been doctored by the uploader. I like it, whatever it is.
