Tony Danza, Rob McClure, Brynn O'Malley, Nancy Opel, David Josefsberg, Catherine Ricafort and other members of the company will celebrate the Broadway-bound musical at the April 7 concert. Show time is 7 PM.

Honeymoon features music and lyrics by Tony Award winner Jason Robert Brown and a book by Andrew Bergman — the director and screenwriter of the original film; the musical was directed at Paper Mill by Gary Griffin with choreography by Denis Jones.

Honeymoon in Vegas, according to press notes, "is an insanely funny musical that tells the tale of Jack Singer (McClure), a guy with an extraordinary fear of marriage, who finally overcomes his phobia and goes to Las Vegas to wed his longtime girlfriend, Betsy (O’Malley). Enter Tommy Korman (Danza), a widowed and unscrupulous gambler looking for another shot at love. Tommy spots Betsy, who bears an uncanny resemblance to his late wife, and the game is afoot."

There is a $35-$40 cover charge and a $25 food and beverage minimum. 54 Below is located at 254 W. 54th Street. Tickets and additional information are available at 54Below.com.
