EVERY OTHER DAY IS CHRISTMAS: Mariah Carey, Jimmy Fallon and The Roots, "All I Want for Christmas"

Mungo Jerry, "In the Summertime"

It's impossible not to smile when I hear this.  Da-do-da-da-da... alright.  I especially love the worm's eye view of the toe tapping.

Art Tatum, "Humoresque"

Great rendition of Dvorak by Mr. Tatum.  Enjoy!
