After a further change of ownership the theatre was slated for demolition in 2002 as part of redevelopment plans. Already it had fallen into disuse, the buildings being used more often as a conference centre than a theatre. A preservation campaign by actors and other supporters attempted to reverse the decision. In April 2003 Ken Livingstone, the Mayor of London, ordered the council to block the demolition. As of March 2005 new plans had been submitted for the redevelopment of the site. Nothing materialised and the building continued to operate primarily as a conference centre. The BBC Concert Orchestra used it for occasional concerts, and the BBC recorded a popular weekly radio show, "Friday Night is Music Night" that showcased musicians such as the violinist Nigel Kennedy and singer Josh Groban. In 2006, music duo Pet Shop Boys played a mid-length set accompanied by the BBC Concert Orchestra and special guests including Robbie Williams, Francis Barber and Rufus Wainwright which was musically directed by Trevor Horn. The show was documented on the audio release entitled Concrete.
