The book is by four-time Tony Award-winner Harvey Fierstein (La Cage aux Folles, Torch Song Trilogy), with music and lyrics by John Bucchino.

In A Catered Affair, Cavenaugh (recently of Grey Gardens) will create the role of Ralph Halloran, the groom-to-be opposite bride Leslie Kritzer in this musical set in 1953 Bronx centered on a family wedding.

Cavenaugh made his Broadway debut in 2003, starring in Urban Cowboy.

In the new show, relationships are strained to their limits "when a couple must decide whether to spend their life savings on a family business or to launch their only daughter's marriage with a lavish catered affair."

The musical is based on the Turner Entertainment motion picture distributed by Warner Brothers and written by Gore Vidal, and the original teleplay by Paddy Chayefsky.
