I had posted something earlier on another thread about this, but INHD (or maybe INHD2), (these are two of the "special" High Def channels on Comcast) has recently been showing a Who live concert film, shot at the Isle of Wight. I'm not sure of the date, but would guess 1969 or 1970. (More or less "Live at Leeds" vintage.) I didn't see the whole show, but a good part of the concert consisted of them playing 90% of Tommy. It is broadcast in 5.1, and the sound quality is not bad, given the age, as well as the fact that Who can be a little "loose" live. Highlight for me is Moon's drumming, both for the obvious enjoyment Moon is feeling, as well as for the sheer exuberance and energy. He's constantly popping briefly to his feet, off his throne, either to get a bit more leverage, or just because he can't just sit there while playing. Townsend is also in good form with his windmill chords and spread-eagle jumps. The one odd note is that John Entwistle is dressed in a Halloween-style skeleton costume, for no obvious reason.
