the Windmill. It closed on 31 October 1964 and was again turned into a cinema. The Raymond Revuebar at No. 11 Walker's Court was a small theatre specialising in striptease and nude dancing. It was owned by Paul Raymond and opened in 1958. The facade supported a brightly lit sign declaring it to be the "World Centre of Erotic Entertainment." Raymond subsequently bought the lease of the Windmill and ran it as a "nude entertainment" venue until 1981. The upstairs became known as the Boulevard Theatre and in 1980 was adopted as a comedy club called "The Comic Strip" by a small group of alternative comedians including Rik Mayall, Dawn French, Jennifer Saunders, Alexei Sayle and Adrian Edmondson, before they found wider recognition with the series The Comic Strip Presents on Channel 4. The name and control of the theatre (but not the property itself) were bought by Raymond's business associate Gérard Simi in 1996. The theatre suffered financial difficulties owing to increasing rent, leading to its closure in 2004. It became a gay bar and cabaret venue called Too2Much; in 2005, Elton John staged a joint bachelor party there with his longtime partner David Furnish in anticipation of their civil partnership. The venue was subsequently renamed to the Soho Revue Bar, but closed in 2009. Soho is a centre of the independent film and video industry as well as the television and film post-production industry. Audio post duo White Lightning (Robbie Weston and Rick Dzendzera) opened two audio post facilities in different parts of Soho in 1986: Silk Sound at 13 Berwick Street, and The Bridge Facilities at 55-57 Great Marlborough Street. Silk Sound is still in operation, but The Bridge was sold to Miloco Studios in 2009, and relocated to the Orinoco Complex at 36 Leroy Street in Greater London. White Lightning also opened a third studio at 16 Dufours Place, called Space Facilities, in late 1995, but it closed the same year The Bridge was sold. Twentieth Century House in Soho Square was built in 1937 for Twentieth Century Fox. The British Board of Film Classification, formerly known as the British Board of Film Censors, has been based in the square since 1950. Soho's key fibre communications network has been managed by Sohonet since 1995, which connects the Soho media and post-production community to British film studios such as Pinewood and Shepperton, along with other locations worldwide
