The first performance will be a gala in aid of TheatreMAD and the Mercury Phoenix Trust. Formed by original founders and volunteers of West End Cares and Theatrecares, TheatreMAD is the theatre industry's new independent charity established to support those people facing hardship as a result of HIV, AIDS and other long-term conditions. An earier version of the show was seen at Leicester Square Theatre last November.

So Jest End is devised and directed by Garry Lake, currently playing Pop in We Will Rock You, with Gareth Ellis (Wicked) as musical director and Rebecca Howell (Billy Elliot, La Cage aux Folles) as choreographer. The show will be narrated by Paul Nicholas (the original Rum Tum Tugger in Cats and veteran of many other West End musicals, from Hair and Jesus Christ Superstar to Grease and The Pirates of Penzance, who is best known for his TV role as Vince in "Just Good Friends"), and the cast includes Rachel Tucker (BBC1's "I'd Do Anything"), Jon Boydon (We Will Rock You), Louise Dearman (Evita on tour) and Ian Carlyle (We Will Rock You), with guests including Ian Kelsey (ITV1's "Emmerdale," Chicago) and Sandra Marvin (Hairspray).
