The July 14 performance will be held in London at The Russell Hotel; show time is 7 PM. In addition to McCarthy, the company will also include Annalene Beechey (Glinda in Wicked), Stephen Carlile (My Fair Lady, The Phantom of the Opera), Claire Winsper (Sunset Boulevard, The Phantom of the Opera), Jonathan Eio (The Best Little Whorehouse in Texas) and American actor Kevin Duda (Little Women national tour). Chad Larabee will direct Ain't We Got Fun, which is based on three short stories by F. Scott Fitzgerald — "Bernice Bobs Her Hair," "Head & Shoulders" and "A Diamond as Big as The Ritz" — and utilizes the songs of Richard Whiting. Among the songs that are featured are "Beyond The Blue Horizon," "My Ideal," "Breezin' Along with the Breeze" and the title tune.

The creative team also includes Todd Underwood (choreography), Michael O'Flaherty (musical arrangements and orchestrations) and Nigel Lilley (musical direction).

The F. Scott Fitzgerald Society is producing the concert for its Annual Gala.

In addition to Evita Siobhan McCarthy has also been seen on the West End stage in Mamma Mia! (Donna Sheridan, Laurence Olivier nomination) and Chess (Florence) as well as in Blood Brothers and Medea. McCarthy was also part of the BBC series "Bad Girls."

Director Larabee recently helmed a production of Singin' in the Rain at Seaside Music Theatre in Florida; he is also developing Lori McKelvey's Civil War musical Georgia.

A backers reading of Ain't We Got Fun is scheduled in fall 2007 in Manhattan. A regional world premiere is likely for spring 2008.
