Aside from the fact that Elmo is at his very cutest in this video with singer Norah Jones — comforting her as she laments the absence of her friend the letter Y — the song itself is a winner, literally. Off her breakthrough 2002 album, Come Away With Me, the original "Don't Know Why" won Jones a Grammy for Song of the Year along with Grammys for Record of the Year and Best Female Pop Vocal Performance.
