The show will have a cast of five. Christian Borle, Betty Buckley and Carolee Carmello have been confirmed. Michael Rupert is also expected to perform, though the Finn veteran (Falsettos) has not been officially connected. Another Finn actor, Norm Lewis, was once attached to the project.

The show, termed a "song cycle," will play Sundays and Mondays in the Newhouse, performing on the set of Observe The Sons of Ulster Marching Towards the Somme during that show's dark nights.

Finn is best known for two musicals: Falsettos, which ran on Broadway, and A New Brain, which played the Newhouse in 1998. Falsettos, an amalgamation of the musicals, March of the Falsettos and Falsettoland, starred Carmello in its Broadway incarnation. Since then, the actress has appeared in A Class Act and Parade.

Buckley's last New York stage performance was in Nicky Silver's The Eros Trilogy at the Vineyard Theatre. She's better known for her Broadway musicals, including The Mystery of Edwin Drood, Cats and Sunset Boulevard.

In addition to Falsettos, Rupert has appeared in Mail and Putting It Together, as well as The Happy Time. Finn's latest project was Infinite Joy, a cabaret retrospective of his work which played at Joe's Pub and starred himself and a variety of performers. Also on Finn's shelf is a musical version of The Royal Family.
