I found this delightful piece of holiday merriment on Bob Cesca's blog. I think that you will enjoy it.
I don't know who this Andy Duva fellow is, but he seems to be an up-and-coming theatre and sketch-comedy actor. This is really good stuff -- apparently it's really him singing -- so I have the feeling we'll see a lot from him down the road.
Since I think that Newt is the surprise Christmas gift that just keeps on giving and giving, this cheery song just puts a spring in my step. And doesn't he look good in that Santa cap?
