It's Christmastime in the city! 44 Charlton -- the only variety show of, by and for the raucous rumpus room that is NYC -- is ringing in mucho cheeros with host Julian Fleisher's Rather Big Band and special guest, Ana Gasteyer. Prehaps you haven't heard that the veteran star of SNL, Mean Girls, Lady Dynamite and People of Earth is also a goddamn great singer with hard nut for the Season of Giving. And she will give until it hurts, people. So get on down to a stone soul Christmas at WNYC and WQXR's Greene Space at, um 44 Charlton Street and prepare to be nogged out!
