I keep returning to this video of Frank Tovey. I think that it is a very special performance and love how he responds to having to lip-sync the lyrics. His actions could easily be seen as a protest for being in the position in the first place, but maybe there is more to it. He seems tuned in to something in way that transforms a boring mimed performance into something powerful and hilarious. I'm sure that everyone involved were pissed off at him, but he carried the performance and made it real in the only way that he could. I think it is perfect.
