Playbill.com has learned that as much as half the cast has been stricken with chest infections during rehearsals of the Jerry Herman (music and lyrics)-Harvey Fierstein (book) show.

Terry Johnson's production features Philip Quast and Douglas Hodge as gay lovers George and Albin, respectively.

The cast also includes American actor Tara Hugo as Jacquline; Neil McDermott (Sound of Music and Bad Girls) as Jean-Michel and Jason Pennycooke (The Gershwins’ Porgy and Bess and Simply Heavenly)as Jacob.

Three-time Olivier winner Quast (Sunday in the Park with George, The Fix and South Pacific) was last seen on the London stage in the revival of Evita.

Actor/director Hodge recently helmed Absurdia at the Donmar Warehouse. He made his musical theatre debut playing Nathan opposite Ewan McGregor's Sky in Guys and Dolls. La Cage aux Folles will be helmed by writer/director Johnson and designed by David Farley, designer of the Menier's award-winning production of Sunday in the Park with George.

La Cage aux Folles premiered at Broadway's Palace Theatre on Aug. 21, 1983, running for 1,761 performances and winning six Tony Awards, including Best Musical, Best Score and Best Book.

The London premiere opened at the Palladium on May 7, 1986, and ran for 301 performances.

Herman's credits include Milk and Honey; Hello, Dolly!; Mame; Dear World; Mack and Mabel; and The Grand Tour. La Cage aux Folles garnered Herman his second Tony Award. His first was for Hello, Dolly!.

Fierstein, who also won a Tony for his work on La Cage aux Folles, is the author of Torch Song Trilogy, for which he won the Best Play and Best Actor Tonys. His new musical, A Catered Affair, will arrive on Broadway later this season.

The London production of La Cage marks the musical theatre debut for the prolific Johnson. His plays include Insignificance, the Olivier-winning Emmanuelle and Dick and, more recently, Hitchcock Blonde. His adaptation of The Graduate transferred from the West End to Broadway.

La Cage aux Folles is based on Jean Poiret's play about middle-aged lovers Albin and Georges, who run a nightclub in St. Tropez, where Albin's alter ego ZaZa is the star attraction.

The plot revolves around the complications that develop when Georges' son announces that he is getting married to the daughter of a local moral crusader and whose parents are coming to dinner to meet the future in-laws.
