'The Sing-Off' recap: One Night with Nick Lachey and his blazers | PopWatch | EW.com: Well, here we are, at the most wonderful time of the year: The Sing-Off is back, and you can never really know for how long, so cherish every minute, even when they all come on the same night. In its fifth season of dodging the eviction notice NBC keeps hiding in Shawn Stockman’s dressing room, The Sing-Off returned as a one-night, two-hour holiday special. And even at just two hours—half the length of a typical singing show’s weekly allotment—I stand by this being the best happiest show on television.
