The show has drawn new audiences to the National

The show has been a sell-out at the National Theatre, and is now moving to the Cambridge Theatre in Covent Garden.

It is based on the US presenter's trashy talk show, and features tap-dancing Ku Klux Klan members, and a chorus chanting four-letter words.

The production has been a big hit for new National Theatre boss Nicholas Hytner, with its run extended twice, and producers say 45% of its audience have been newcomers to the venue.

Now producers are making 35,000 top-price tickets available at a reduced rate for under-25s when the show moves to the Cambridge on 14 October.

"We think it is vitally important to get more young people into the theatre, and it is a show which has proved hugely appealing to a younger audience," said a spokesman.

The show, written by Richard Thomas and Stewart Lee, started at the Battersea Arts Centre in south London last year, before being picked up by the National.

Lee joked: "I am delighted to be going to the Cambridge Theatre with Jerry Springer - The Opera, as it is easily reached via the 73 bus from my home in Hackney."

Composer Richard Thomas added: "The one good thing about opening in the West End is... everything."
