In Fact: this music, written for the first UK series of Big Brother back in the summer of 2000, was composed by Paul Oakenfold with Andy Gray under the pseudonym (used for the first and last time) of Element Four. The copyright is separate to that of the Big Brother concept, and permission to use it in Bad Wolf was aquired only at the eleventh hour - along with Divina McColl's narration - following director Joe Ahearne's second request to the rights holders.
Oakenfold made his name remixing tracks for artists such as U2, M People, Simply Red and the Stone Roses, and compiling Ministry of Sound albums, before graduating from house music towards a melodic, commercial style of trance, particularly through his residency at the UK's Cream. In 1999 the Guinness Book of Records listed him as the World's Most Successful DJ, and his theme for Big Brother - composed later that year - continues to sell well with each new series of the television phenomenon.
The Weakest Link and What Not to Wear segments also featured backing music; the latter appears to have either been taken from stock or specially composed by Murray Gold, whilst the former – although completely and utterly true to the original programme, as seen around the world – has never been commercially released, so we have nothing more to say about it!
