Kathy Burke, whose production of Sam Shepard’s The God of Hell is currently playing at the Donmar, will direct the piece.

French and Moyet will play two sisters whose mother is disabled. While Moyet’s character sings in bars on Spain’s Costa Del Sol, French’s role is that of a school teacher who is also responsible for caring for the sisters’ mother. Moyet has written new music for the show, in which she will also sing.

After a UK-wide tour, the show is due to open at the West End’s Lyric theatre on April 4, 2006, following a week of previews.

French is best known as the larger half of the TV comedy duo “French and Saunders." She was last seen in the West End in 2003 in My Brilliant Divorce, and made her Shakespearean debut two years earlier as Bottom in Matthew Francis’ production of A Midsummer Night’s Dreamat the Albery.

Moyet first became well known in the eighties band Yazoo. The pop singer made her theatrical West End debut as Mama Morton in 2001 in the successful West End production of Chicago. Like French, Burke attained celebrity status as a comedy actor on British television. In a long-running sketch show Burke starred alongside comedian Harry Enfield, played a vulgar flat-mate in the sitcom “Gimme, Gimme, Gimme” and made notable appearances in the films “Elizabeth” and “Nil By Mouth.”

But over the last few years Burke has carved out an increasingly impressive career as a stage director, compiling a list of directorial credits including a well received production of Brendan Behan’s The Quare Fellow for Oxford Stage Company.
