John Lennon, Yoko Ono, and the Plastic Ono Band - Happy Xmas (War Is Over)

In light of John Lennon's 20th death anniversary, I've been listening to quite a lot of his songs the past few months. One of my musically-inclined office mates introduced me to John Lennon's Happy Xmas. Just like all the Lennon songs, it was love at first hear.

Happy Xmas is my 2010 Christmas song!
