"Harvest" as performed by Rufus Wainwright and Chris Stills
A lot of the lyrics don't make a lot of sense, but you gotta give credit where it's due: Dream up, dream up/Let me fill your cup/With the promise of a man is some awfully nice recombinant concision. The song is what I imagine a serenade is, full of hope and sadness and delivered from a place you can't see. I have no idea who is being serenaded, but I do know that the two beautiful human voices on this version are your heart's enemy (they break it mercilessly for three solid minutes and then some), but your brain's pal (they help it understand why evolution might have come up with lungs and tongues and teeth and larynges and vibrating membranes inside the dark safety of our bodies).
(No disrespect to Chris Stills, who is perfect in this number, but whenever I hear Rufus Wainwright sing, I want to bring him home and take care of him until one of us dies.)
