When one thinks of great Christmas songs, they often think of duets.
Bing Crosby and David Bowie's "The Little Drummer Boy."
Dolly Parton and Kenny Roger's classic holiday record, "Once Upon a Christmas."
Hall & Oates genius turn on "Jingle Bell Rock."
But one of my favorite holiday duets comes from a somewhat unlikely pairing -- Coldplay frontman Chris Martin and late night host Conan O'Brien.
Whenever I hear "Have Yourself a Merry Christmas," I can't help but think of Martin playing the piano while Conan sings along,adding some ... distinct vocal flourishes to this holiday classic while donning a ghastly, bright red Christmas sweater.
It's very funny but also oddly sweet. Enjoy.
