Watch Chris Martin sing Christmas carols with Garrett Hedlund

There was a conspicuous absence at Sunday's festive Unbroken brunch, held in Los Angeles at posh eatery Fig & Olive. As castmembers Jack O'Connell, Garrett Hedlund and Miyavi mingled with Academy voters, Angelina Jolie was absent, having bowed out of promotional activities on Friday due to a bout of chicken pox. No matter, Chris Martin was there to fill the void, and took the stage for a special performance of Miracles, a song Coldplay wrote for Unbroken. "I left a tip jar at the front," the musician joked, before launching into the song. While the ballad was beautiful, it was a surprise Christmas duet spurred on by Hedlund that really got the crowd going.

Enjoy Martin singing Miracles, Viva La Vida, and White Christmas with Hedlund -- and feel the holiday spirit wash over you. (Watch out for some mild cursing, particularly when Martin jokingly tells voters present he doesn't give a [expletive] if they vote for the song.) Ah, musicians. You delightfully antagonistic bunch.
