Sheffield exists to promote chamber music. It describes itself as the largest promoter of chamber music outside London. Sheffield has two large theatres, the Lyceum Theatre and the Crucible Theatre, which together with the smaller Studio Theatre make up the largest theatre complex outside London, located in Tudor Square. The Crucible Theatre is the home (since 1977) of the World Snooker Championships and hosts many well-known stage productions throughout the year. The Lyceum, which opened in 1897, serves as a venue for touring West End productions and operas by Opera North, as well as locally produced shows. Sheffield also has the
Phillip Street Theatre revues, including Gordon Chater, Barry Creyton, June Salter, Wendy Blacklock, writer John McKellar and writer-producer James Fishburn. The Phillip Street revues ended in 1971 when the Phillip Theatre changed hands and became the Richbrooke then the Rivoli (when leased briefly by Hoyts), then the Mandarin Cinema, Mandolin and finally Dave's Encore. The building has now returned to its original form of the Australian Hall. Note that the Phillip Street Theatre, separately to Orr's Phillip Theatre, recommenced operations in 1963 following the completion of a 300-seat theatre within the office block which replaced the 1961 demolition.
