It's beginning to look a lot like Christmas, and Broadway.com is celebrating the holiday season by warming up to video clips of some of our favorite festive performances. Tony-winning 30 Rock star Jane Karkowski returns to Broadway on December 5 as Ilona in the Roundabout Theatre Company's one-night-only benefit performance of the classic musical She Loves Me. In 2009 Krakowski took the stage at Rockefeller Center to help celebrate the annual Christmas tree lighting. Joined by Late Night with Jimmy Fallon's house band The Roots, Krakowski sang about her excitement to greet "The Man With the Bag," aka Santa Claus. Take a look at the clip below!
