Broadway nightspot 54 Below rang in the holiday season on December 20, kicking off The 6th Annual Joe Iconis Christmas Spectacular, an environmental rock-and-roll concert-revue that has become a cult favorite. Directed by John Simpkins and produced by Jennifer Ashley Tepper, the show, hosted by Drama Desk nominee Iconis, features a cast of 50 and special guests including Santa Claus, Jesus, Charles Dickens, Broadway stars Susan Blackwell ([title of show]), Julia Murney (Wicked), Krysta Rodriguez (First Date), and Annie Golden (Xanadu). Songs include Christmastime favorites like "Santa Baby," "Baby, It's Cold Outside," "Hard Candy Christmas," and "Fairytale of New York," along with a few of Iconis' own compositions. The show continues at 54 Below with two more shows on December 21, at 8:00pm and 11:00pm.
