The London Chamber Orchestra (LCO) is the longest established professional chamber orchestra in the United Kingdom. Based in London, LCO has a residency at Cadogan Hall in Sloane Square and regularly tours Asia, the UK, Europe and the United States. 　　The London Chamber Orchestra was founded in 1921 by the English conductor, organist, pianist and composer Anthony Bernard. He conducted the LCO's first performance, in the salon of No. 4 St. James's Square on 11 May 1921. 　　LCO's patron is the Duchess of Cornwall. The LCO performed at Buckingham Palace at the invitation of the Prince of Wales in April 2006, and has performed for the Queen at Kew Palace. 　　In April 2011 it was announced that the London Chamber Orchestra would perform at the wedding of Prince William and Catherine Middleton at Westminster Abbey on 29 April 2011. The special programme of music was conducted by Christopher Warren-Green, who also conducted at the weddings of Prince Charles and Camilla Parker-Bowles, and Prince Harry and Meghan Markle. Music played at the royal wedding was recorded and released digitally by Decca Records on 5 May 2011. 　　The LCO has given more than 100 UK premieres, including works by Malcolm Arnold, Manuel de Falla, Gabriel Fauré, Leoš Janáček, Maurice Ravel, Ralph Vaughan Williams, Igor Stravinsky, and, most recently, Graham Fitkin and James Francis Brown. In 2006 the LCO premiered Sir Peter Maxwell Davies's The Golden Rule, written to mark Queen Elizabeth's 80th birthday. 　　The LCO receives no grants and is not supported by any public body. Instead, the orchestra depends upon its audiences and on the support of corporate sponsors and donors. These include Omers PE, RWE Dea, and Lazard.
