Performances will run Feb. 27-March 2 under the direction of Tony Award winner John Rando (Urinetown, A Christmas Story). Rob Fisher (Encores!, Anything Goes) will conduct the New York Philharmonic Orchestra.
The lushly scored classic centers on a tempestuous love affair between gruff carnival barker Billy Bigelow, to be played by Gunn (Camelot, Show Boat, Billy Budd), and the young millworker Julie Jordan, to be played by four-time Tony Award nominee O'Hara (The Light in the Piazza, South Pacific, Nice Work If You Can Get It).
Additional casting is expected shortly.
Warren Carlyle (Chaplin, Follies), who recently collaborated with Rando on A Christmas Story, will choreograph the concert staging.
Carousel has music by Richard Rodgers with a book and lyrics by Oscar Hammerstein II. It is based on the play Liliom by Ferenc Molnar. The classic features such songs as "If I Loved You," "June Is Bustin' Out All Over," "What's the Use of Wondrin'?," "You'll Never Walk Alone," "Mr. Snow" and "Soliloquy."
