Viva La Diva is a song and dance extravaganza starring international opera superstar Katherine Jenkins and Prima  Ballerina Darcey Bussell. The spectacular show, which plays homage to the great stage and screen divas of the past,  has been filmed especially for DVD at London's O2 as part of the recent UK Arena tour.  Directed by choreographer Kim Gavin, who has worked previously with the likes of Take That, the show sees two of Britain's  best loved and admired stars stretching the disciplines they are best known for as well as swapping roles, with Katherine  dancing and Darcey singing for the very first time.    Viva La Diva was filmed before a sell out audience at London's O2 Arena and features extras including an interview  with Katherine and Darcey.
