Elvis Presley's 'Blue Christmas' is a Christmas classic, and should should be left alone, right?

Being a big Elvis fan myself, I would be the first to say, leave it alone.  Unless you're Elvis Presley, don't try this at home.  However, this young man blows it out of the water and when you watch the video, you'll understand why his performance is so impressive.
