The Queen's Diamond Jubilee concert 2012. The Diamond Jubilee Concert was a British music concert and celebration held outside Buckingham Palace on The Mall in London on 4 June 2012. The concert was organised by Take That singer-songwriter Gary Barlow and was part of Queen Elizabeth II's Diamond Jubilee celebrations. The Diamond Jubilee Concert followed two concerts held at the palace for the Queen's Golden Jubilee a decade earlier – the classical themed Prom at the Palace and the pop/rock themed Party at the Palace. The concert was partially attended by the Queen, who arrived at 9 pm, but not by Prince Philip who had been taken to hospital with a bladder infection earlier in the day. Prince Charles and other members of the royal family attended the whole concert.
