One can easily say more negative things than positive about this concert DVD, but let me insist at the outset that the small number of positives unquestionably outweigh the many negatives.  At the heart of the disc is a phenomenal live performance by the Who in 1970, when they were at their instrumental height, and before the excesses of the sixties and seventies began taking their toll on the playing and hearing of the quartet.  Yes, there are many things to carp about, but in the end it all comes down to the fact that these guys were flat out superb that evening.  Although much of the end of the concert consists of a performance of highlights from TOMMY, most of the concert on the DVD (more about the contents in a bit) contains a host of covers, all of them stunning.  While all of the band members are outstanding, Pete Townshend (who was ironically of the three musicians the least virtuosic, both Moon and Entwistle having few peers) always seems able to steal the show with his helicopter power chords, brilliantly inept dancing, and congenial lunacy.  I am not generally a fan of concert DVDs, but I had a whale of a time with this one.
