Presented by the League of American Theatres and Producers, Inc., the new initiative will celebrate "Broadway's most loyal group of theatre-goers," according to an announcement.

The evening will include show discounts and a charitable tie-in with the Phyllis Newman Women's Health Initiative of the Actors Fund of America. A special free party will be held at Spotlight Light (5-7:30 PM), which will feature Women-in-Theatre panels and Broadway karaoke.

In a statement League executive director Charlotte St. Martin said, "Women represent 63% of Broadway audiences and 66% of ticket purchasing decisions so Ladies Night is our way of saying thank you. And we hope that the activities provided free this evening will remind our most loyal members about the variety of Broadway offerings and will give this very engaged demographic yet another reason to join us for an additional night on Broadway full of fun and entertainment. Women are also the primary decision makers when it comes to purchasing theatre tickets and planning a night out on the town, and we are delighted to host for them what we hope will become an annual event that educates them, pampers them, rewards them and just reminds them about how much we appreciate their loyalty to Broadway!"

Xanadu co-stars Jackie Hoffman and Mary Testa are the event's spokespeople. In a statement the comedic duo said, "We're honored to be the spokesgals for Ladies Night Out on Broadway because not only do we get to help raise money for women's health, we get to introduce new audience members to the exciting world of live theatre."

Participating Broadway shows include A Chorus Line, The Color Purple, Curtains, Hairspray, Legally Blonde the Musical, Les Misérables, Mamma Mia!, Mary Poppins, Monty Python's Spamalot, The Phantom of the Opera, The 25th Annual Putnam County Spelling Bee and Xanadu; participating Off-Broadway shows include The Fantasticks and Stomp.
