Special guest appearances by additional Broadway stars will be announced at a later date.

A live auction showcasing exclusive Broadway opportunities and packages will also be offered. Some of the items featured in the auction include orchestra seats to The King and I and a meet-and-greet with Kelli O'Hara.

Tyler Paul, co-founder and executive director of The Northeast Children's Theatre, said in a statement, "We are honored to have this incredible roster of stars joining us. Between the concert and the auction, we hope this will become the ultimate one-night-only gathering for fans of Broadway."

Proceeds from the Gala will benefit artistic programming for school audiences, as well as educational initiatives for underserved children in disadvantaged communities.

The concert will begin at 8 PM at The Branson Hall in Westport, CT.
