Hi Kids: For me it's KD Lang, hands down. For Style, Class, Voice, Articulation, Emotion, and Delivery. It is a rendition that will be remembered. I see Leonard Cohen saying, "Thanks K.D.!" Buckley's is O.K., but not in the same league. Since K.D.'s video has been posted, I'll put up Buckley's for comparison...

He seems to be struggling with it, maybe some of you hear that as "emotion", not me. And, there are parts in there that make me cringe. I'll pass on Buckley...
