Best Performance Of One Song Ever Witnessed

[Simple Torture]

So, out of all the concerts you've ever been to, what one performance of a single song has blown you away more than any other? This could be because the band/artist just nailed it, or maybe the crowd went nuts, or maybe it just happened to be a particularly cathartic moment. Did it happen to be at the best show you've ever been to, or was it your favorite band, or were you surprised by which band/which show it was? Don't pick more than one! Be a man or a woman and just pick one song (that should make it harder). YouTube clips whenever possible!

Neil Young playing A Day in the Life, feeling every moment and climaxing it by tearing the strings from his guitar and roaming the stage, playing different instruments to see how they interacted with the squealing feedback. Nothing else is even close to that.

Standing on state with Bob Dylan's backing band as they played an instrumental version of Not Dark Yet and the sun started its dip into the horizon was a pretty affecting moment. And it's a cheat on the topic, but any concert where you get the run of Jesus Gonna Be Here -> Shore Leave -> Goin' Out West -> Cemetery Polka -> Come On Up To The House is pretty damn awesome. To justify....Goin' Out West from that show is this one here:

This is a tough one to answer.

I may have to give it to PJ performing "Do The Evolution" at MSG 7/8/03.

It had already been an incredible evening at the Garden, the energy of the band and audience during this performance was something I don't think I've experienced before or since at any concert.

November 28, 1989 in Albuquerque. Stevie Ray Vaughan playing Little Wing drenched in sweat. 10 months later he was dead.

This isn't the exact performance, but still pretty good.

I saw The Who in about 1980. They did a one song encore, The Real Me. I've never seen or heard anything so perfectly executed. Pure, undistilled aggression for four minutes or so.
