I'm not that into them now, despite having gone through a Who-loving phase as a teenager -- the movie Quadrophenia came out when I was 16 -- but their performance of "A Quick One While He's Away" on the Rolling Stones Rock And Roll Circus TV show (1968, now on DVD) cannot be denied.

You will see Moon rocking the shit out of a song that had about 20 different parts, none of which repeat, while flailing around, smiling like a maniac, singing along, nailing each part, basically looking like the happiest kid ever on his happiest birthday ever.
A sidenote regarding this performance: it was done on what was supposed to be a big TV show called "The Rolling Stones Rock 'n Roll Circus." The Stones were supposed to be the stars, see. But after screening the film, the Stones realized that they'd been completely blown off the stage by the other participants, particularly the Who, to where they decided to scrap the whole thing! It was never aired!
One of the very best rock'n'roll performances on film or video, if not THE best, I've ever seen.
