Eric, good to see you here!
I'm convinced that the most powerful performances are those close to the edge. You get as involved emotionally as you can without losing it. Sometimes you DO go over the edge, but the folks listening are right there with you. You don't take them anywhere if you play it safe. I heard Paula miss a couple words and keep going. It was insignificant - eclipsed by the power of that song and her singing, and that's what I remember most. Everybody makes mistakes. Few people can put the passion and strength and beauty into the music the way Paula does.
