Holbrook, an original cast member of Xanadu, will return to the production to play Sonny July 1-27. Jackson will resume performances at the Helen Hayes Theatre July 29.

Curtis Holbrook created the roles of Thalia and Young Danny in Xanadu but left the production to be part of the upcoming new musical Saved at Playwrights Horizons. His other Broadway credits include All Shook Up, The Boy From Oz, Taboo, Fosse and Footloose. Holbrook was also seen in the film of "Hairspray."

In addition to Jackson, Xanadu features Kerry Butler, Tony Roberts, Jackie Hoffman, Mary Testa, Kenita Miller, Patti Murin, Kyle Dean Massey and Andre Ward.

Xanadu boasts a book by Little Dog Laughed playwright Douglas Carter Beane — a 2007 Tony Award nominee — and utilizes songs from John Farrar and Jeff Lynne's film soundtrack. The musical, according to press notes, "tells the story of one of the nine muses of ancient Greece who comes to earth to inspire the greatest of artistic achievements – a roller disco. Along the way she falls in love, bumps into an old acquaintance and for the first time, feels the desire to create herself."

Xanadu recently received six Drama Desk nominations, including Best Musical, Best Book (Douglas Carter Beane), Best Director (Christopher Ashley), Best Actor (Cheyenne Jackson), Best Featured Actress (Mary Testa) and Best Choreography (Dan Knechtges). The show also received Best Musical nominations from the Outer Critics Circle and the Drama League. Kerry Butler and Cheyenne Jackson are nominated for Outstanding Performance Awards from the Drama League.

The Xanadu cast recording is available on the PS Classics label.
