For those without family to see—or with family who don’t want to see them—the holidays can be a drag. Cue the pencil-mustached entertainer Murray Hill, who created a Christmas variety show for this subpopulation in New York City twenty-five years ago. Since then, “A Murray Little Christmas” has found a wider audience, as has Hill in other endeavors, including a role on HBO’s “Somebody Somewhere.” That show’s stars, Bridget Everett and Jeff Hiller, performed at last December’s iteration; this year, expect more celebrity guests, holiday songs backed by an eleven-piece band, and a choir or two, with Hill’s risqué humor and warmth stringing everything together. Suggested attire: festive, fancy, or, for those on the naughty list, furry suits.—Dan Stahl (Alice Tully Hall; Dec. 19-20.)Post-Punk
