The original cast from cult musical The Rocky Horror Show is to reunite for a charity performance marking 50 years of theatre at London's Royal Court.
Richard O'Brien updated the script while maintaining its original feel
Richard O'Brien, who played Riff Raff, will appear on stage with Patricia Quinn - now Lady Stephens - and Nell Campbell as Magenta and Columbia.
Several guest stars, including Anthony Head, Toyah Willcox and Christopher Biggins, will join them.
The show was voted the venue's most enjoyable ever piece of theatre.
A total of 16,000 of its mailing list members were invited to take part in the poll, and Royal Court management had agreed to stage the resulting favourite.
The survey was organised to coincide with the 50th anniversary of the theatre's first performance, John Osbourne's Look Back in Anger, on 8 May 1956.
The Royal Court has gained an international reputation for its commitment to finding innovative work and new talent, and for promoting young writers, actors and directors.
Guest performers confirmed
West End veteran Michael Ball, comedian Adrian Edmondson and singer Stephen Gateley are among the performers confirmed for the one-off Rocky Horror Show reunion.
Guest narrators will include broadcaster Jamie Theakston, former ice skater Robin Cousins and Steve Pemberton from cult TV series The League of Gentlemen.
"Richard O'Brien kindly agreed to rewrite certain parts and to go back and make amendments to give it a fresh look and a fresh feel, as well as keeping it in the spirit of how it was originally intended," said theatre spokesman Ewan Thomson.
The original Rocky Horror Show from 1973 - featuring songs such as The Time Warp - was adapted into a film.
This was released two years later and starred Tim Curry and Susan Sarandon.
'Reflecting original version'
A second version of the theatrical show was later created which used the movie as its inspiration.
However, Mr Thomson said Wednesday's performance would "bring it back to the version of the Rocky Horror when it was originally done at the Royal Court 33 years ago".
He added the response from theatregoers had been overwhelmingly positive and said "the box office went bananas" when tickets were released.
Proceeds from ticket sales will be shared between the Royal Court and Amnesty International.
