The opening ceremony of the 2015 Rugby World Cup took place at Twickenham Stadium in London on 18 September 2015 at 19:20 (BST). The ceremony told the legend of how William Webb Ellis created the sport of rugby union, and featured the choir of Rugby School singing "Swing Low, Sweet Chariot", an anthem of rugby union in England. All the participating teams were represented by a former player in the ceremony; the host nation, England, was represented by World Cup-winning captain Martin Johnson. The ceremony was directed by Kim Gavin, who was also responsible for directing the closing ceremonies of both the 2012 Summer Olympics and the 2012 Summer Paralympics. Prince Harry, Duke of Sussex, who had an acting part previously in the ceremony, declared the tournament officially open, ending his speech with the words, "We're ready. Game on." British Prime Minister David Cameron said on social media that the 2015 Rugby World Cup would be the best ever.
