In addition, the full cast album will be released May 9, through Really Useful Group and Polydor Records. There will also be a small increase in the top ticket price, from the current top price of £62.50 to £65, beginning Sept. 18.

The show, directed by Jeremy Sams, choreographed by Arlene Phillips and designed by Robert Jones, reunites the principal creative team behind Lloyd Webber's 2006 London Palladium production of The Sound of Music, and like that production, the young actress playing Dorothy has been chosen by public vote on a reality TV casting show, "Over the Rainbow," for which Lloyd Webber was the lead judge. The winner was Danielle Hope, who plays Dorothy at most performances, with Sophie Evans – runner-up to Hope – taking over on Tuesday evenings and during Hope's holiday weeks, May 3-8, Sept. 5-12, Oct. 30-Nov. 6 and Dec. 14-18.

Also starring is Michael Crawford, who plays the title role of The Wizard, who was last seen on the London sage in Lloyd Webber's original production of The Woman in White, and is best known for originating the title role in Lloyd Webber's The Phantom of the Opera in both the West End and on Broadway. He has previously appeared at the London Palladium in the title role of Barnum. Film roles include starring in the film version of Hello, Dolly!, subsequently immortalized in the animated feature "Wall-e," and on TV he is best known for playing Frank Spencer in the sitcom "Some Mothers Do 'Ave 'Em."

The cast also features Edward Baker-Duly as the Tin Man, David Ganly as Lion, Paul Keating as Scarecrow, Emily Tierney as Glinda and Hannah Waddingham as the Wicked Witch of the West. The show is produced by Andrew Lloyd Webber and Bill Kenwright.
