Live from Roseland Theater in Portland, OR., Jimmy Fallon takes the stage (who knew!?) to rock out a Christmas song in celebration of the approaching holiday. Highlight? Guest appearance of Jack Black of course.

I’m a little iffy on what music talent Jimmy Fallon has, but after School of Rock, I would buy a rock album tomorrow if it was made by Jack Black. He really knows how to rock it with a style mixed with Meatloaf and Aerosmith.

Just a fun way to say Merry Christmas, or Happy Christmas depending on where you live. The performance would have been nothing without Jack… Jack to save the day! Merry Christmas everyone.
