One of the West End's most popular and enduring shows is being usurped by a new kid on the block as Chicago the Musical exits the Cambridge Theatre to make way for Matilda.

The RSC production of Roald Dahl's much-loved story of the little girl with the extraordinary imagination (and uninspiring parents) is moving to London after a sell-out season at The Courtyard Theatre in Stratford-upon-Avon, and barging Chicago out of its West End nest in the process.

This musical version of Dahl's classic, by Dennis Kelly and Tim Minchin, promises to thrill mums, dads, kids and aspiring Matildas everywhere with riotous laughs, a tremendous score and trademark Dahl moments of poignancy, all in one of the West End's best theatres.

The creative team and the cast from the original Stratford Avon show will come together to produce the London show, previews for which start on 18th October 2011.

Adult cast members reprising their Stratford roles for the Cambridge Theatre run include Bertie Carvel (Miss Trunchbull), Paul Kaye (Mr Wormwood), Josie Walker (Mrs Wormwood) and Lauren Ward (Miss Honey).

Tickets for the show which will (currently) run from October through to February 2012 go on sale on Saturday 21st May at midday, starting at just £15.

The last performance of Chicago at the Cambridge will be on Saturday 27th August. But Billie Flynn fans shouldn't despair - it is believed negotiations are underway to find the show a new West End home.
