"  Before you head home tonight, get into an extra joyous mood by watching Christina Perri rock out with more than a dozen of her personal pals to &amp;quot;Happy Xmas (War Is Over).&amp;quot; The classic holiday song receives an update thanks to Perri&amp;#039;s smooth croons, and the track is part of her A Very Merry Perri Christmas EP, which was named one of Billboard&amp;#039;s top 10 Christmas albums of 2012. \u2028 &amp;quot;When I was recording this song I knew I wanted to have a big gang vocal at the end,&amp;quot; Perri told ELLE.com. &amp;quot;Instead of having children sing, I decided to invite all of my closest singer friends who happened to be in town. About 15 people showed up, and we had a blast. We wore Santa hats, stood around one microphone, and all sang together. It was so much fun and a day I&amp;#039;ll never forget.&amp;quot; See the merry gang take the mic, below. "^^<http://www.w3.org/2001/XMLSchema#string>
