'Glee'

In tonight's holiday-themed episode ("Extraordinary Merry Christmas"), the members of New Directions are asked to perform at two different events on the same day. Will it all work out? Will they sing about it? Even if you've never watched an episode, I think you can answer this one. 8 p.m. Tuesday on Fox (seattletimes.com/tvlistings).
