Stars including Anthony Head and Adrian Edmondson have joined original Rocky Horror Show cast members for a charity performance of the cult show.
Richard O'Brien was one of the original cast members to take part
Richard O'Brien, who played Riff Raff, appeared on stage with Patricia Quinn - now Lady Stephens - and Nell Campbell as Magenta and Columbia.
The performance marked 50 years of London's Royal Court Theatre, where the musical was first staged 33 years ago.
Fans, many dressed in costumes, paid up to £350 for tickets.
The show, in aid of Amnesty International UK, was narrated by Jamie Theakston and Steve Pemberton from The League of Gentlemen.
Richard O'Brien said: "There couldn't be a better cause for Rocky Horror to support than Amnesty, which continues to defend free expression and stand up for people's rights all over the world."
The Rocky Horror Show ran for several weeks at the Royal Court in 1973 before moving to a new venue.
It was adapted for cinema as The Rocky Horror Picture Show in 1975 and has generated an enthusiastic and dedicated following.
The show was recently voted the theatre's most enjoyable piece of theatre ever.
A total of 16,000 of its mailing list members were invited to take part in the poll, with Royal Court managers agreeing to stage the winner.
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.
