Live Aid was a multi-venue benefit concert and music-based fundraising initiative held on Saturday 13 July 1985. The original event was organised by Bob Geldof and Midge Ure to raise further funds for relief of the 1983–1985 famine in Ethiopia, a movement that started with the release of the successful charity single "Do They Know It's Christmas?" in December 1984. Billed as the "global jukebox", Live Aid was held simultaneously at Wembley Stadium in London, attended by about 72,000 people, and John F. Kennedy Stadium in Philadelphia, attended by 89,484 people.

"Do They Know It's Christmas?" is a charity song written in 1984 by Bob Geldof and Midge Ure to raise money for the 1983–1985 famine in Ethiopia. It was first recorded by Band Aid, a supergroup assembled by Geldof and Ure consisting of popular British and Irish musical acts. It was recorded in a single day at Sarm West Studios in Notting Hill, London, in November 1984.
