The one night-only event will also include a performance by Michael McElroy and the Broadway Inspirational Voices.

The evening is being presented by the Actors' Fund in association with Sh K-Boom Records. In a statement Sh-K-Boom President Kurt Deutsch said, "With the exception of Radio City’s Rockettes and the Rockefeller Center Tree Lighting, New York has no annual event to commemorate the Christmas season, certainly none from the Broadway community. We aim to create a new and joyful holiday tradition for the City with our yearly Benefit concert, bringing together Broadway’s best and brightest stars, every Christmas, for a great cause." Paul Dobie and Lisa Leguillo will direct the benefit.

Tickets range from $50-$1,000 and are available by calling (212) 221- 7300, ext. 133. For more information visit www.actorsfund.org. The New Amsterdam Theatre is located on West 42nd Street.
