Jack, Wil Holt's musical about President John F. Kennedy's relationship with his father, magnate Joseph Kennedy, will open in Dublin April 21, 1997, with a West End production being discussed before a Broadway opening in 1998.

Jack, with a score by Holt (The Me Nobody Knows) and book by Tom Sawyer will open a 12-week engagement at Olympia Theatre in Dublin. No theatres have been announced for London or New York.

The musical was developed in a 1994 workshop at Goodspeed Opera House's Norma Terris Theatre (where Andrew Lloyd Webber's By Jeeves opened Nov. 7), with Michael Brian as JFK and Casper Roos as Joe. The show subsequently was performed at the University of Oklahoma in 1995. John Cullum's name had been floated for the role of Joe on Broadway around that time, but no casting has been announced for the upcoming production. Casting reportedly will begin shortly in Ireland and the U.K.

Larry Fuller (Evita) will choreograph the show, produced by Isobel Robins Konecky, Stewart F. Lane and Max Weitzenhoffer.

Jack traces JFK's life from his teen years, through World War II, the Senate, the presidency and his assassination in 1963.
