In what’s becoming a charitable tradition, the Killers have released their second Christmas single in as many years. And this time there’s a video! In color, in case “Shadowplay” didn’t do it for ya. Last annum’s gift was “A Great Big Sled,” which we’d have called an overblown affair if it weren’t, ya know, for charity and all. But this year’s present, “Don’t Shoot Me Santa” is a little better, a little cuter — something like The Boss meets Bad Santa, with a dash of Raising Arizona thrown in for good measure. “I saw B. Flow ditching Santa Claus,” etc.
