American Idol - "You're Out. Now Sing!"

No, this isn't a post about how unfair it is to make the person who just got booted out of the competition to sing one last song. This post is about how that one last song often turns out to be the performer's most emotionally honest performance.
Last night's final performance by Brooke was, of course, a mess as she sang through tears and snot and little walls tumbling inside her brain. Yet, there were aspects of it that made it a wonderfully touching performance, despite the wrong notes, the missed lyrics, etc.

If I was ever in a position to instruct the performers, I'd constantly be telling them "when you perform your song, you need to find a way to get to that emotional place you'd be in if you've just been booted off the show. Inform your performance with that emotion."
