Radio City Christmas Show'Tis the season to see holiday-themed theater. For decades, the ultimate Christmastime show has been the Radio City Christmas Spectacular, which continues to bring eager audiences in by the droves to Radio City Music Hall at Rockefeller Center to see the world-famous Rockettes. But in recent years, other holiday shows such as a stage version of Dr. Seuss's How the Grinch Stole Christmas and a new musical of A Christmas Carol have turned up in New York City in November and December. This year we have Cirque du Soleil's winter wonderland of a show, Wintuk, and at the Marquis Theater on Broadway Irving Berlin's White Christmas has returned for another limited holiday engagement. These shows are closing by New Year's or shortly thereafter, so if you want to get into the holiday spirit Broadway-style, you should act fast. If you miss them, they may very well be back - and, if not, they will have likely been replaced by something similarly jolly.
