David Cook just sang "The First Time I Ever Saw Your Face" on American Idol. Johnny Cash did a poignant cover of this Roberta Flack song on his second last album. Listen below: The flaws in Cash's voice only make his cover, I think, more extraordinary and touching and haunting.
Cash died soon after his wife June Carter did, and can't you just hear him thinking about HER as he is singing THIS.
I really liked Cook's version, too.
