Since it's confirmed that PI video is Gaga giving a performance, what "performance" music videos are your favorites?  (Please note, I'm asking about videos where a performance is the primary music video, not your favorite live performances in general) A few of mine are below... one thing that really excites me about this video concept is that it was a staple of early MTV. Gaga is really going to take us back to basics with this and I'm here for it!!
