Concert for Diana was a concert held at the newly built Wembley Stadium in London, United Kingdom in honour of Diana, Princess of Wales, on July 1, 2007, which would have been her 46th birthday. August 31 that year brought the 10th anniversary of her death. The concert was hosted by Diana's sons, Princes William and Harry, who helped to organise many of the world's most famous entertainers and singers to perform. Proceeds from the concert went to Diana's charities, as well as to charities of which William and Harry are patrons.[1] The concert was broadcast in 140 different countries across the world[2] with an estimated potential audience of 500 million.[3][4] In December 2006, 22,500 tickets were made available for purchase for the concert, selling out in just 17 minutes,[2] while 63,000 people turned out to Wembley Stadium to watch the performances to commemorate Diana.[2][5][6] At the end of the performances, a video montage of Diana as a child was presented, accompanied by the Queen song "These Are the Days of Our Lives".[7] The concert started at 16:00 BST and finished at approximately 22:15 BST – there were two short intermissions during the concert.[8] A 2-Disc DVD set of the full concert was released on 5 November 2007. A Blu-ray high definition release of the full concert and documentary was released in November 2008.
