The Live Aid benefit concert takes place in London and Philadelphia, as well as other venues such as Moscow and Sydney.

Live Aid was a two-venue benefit concert and music-based fundraising initiative held on Saturday 13 July 1985. The 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 and John F. Kennedy Stadium in Philadelphia.

A benefit concert or charity concert is a type of musical benefit performance featuring musicians, comedians, or other performers that is held for a charitable purpose, often directed at a specific and immediate humanitarian crisis.

London is the capital and largest city of both England and the United Kingdom, with a population of 8,945,309 in 2023. Its wider metropolitan area is the largest in Western Europe, with a population of 15.1 million. London stands on the River Thames in southeast England, at the head of a 50-mile (80 km) tidal estuary down to the North Sea, and has been a major settlement for nearly 2,000 years. Its ancient core and financial centre, the City of London, was founded by the Romans as Londinium and has retained its medieval boundaries. The City of Westminster, to the west of the City of London, has been the centuries-long host of the national government and parliament. London grew rapidly in the 19th century, becoming the world's largest city at the time. Since the 19th century the name "London" has referred to the metropolis around the City of London, historically split between the counties of Middlesex, Essex, Surrey, Kent and Hertfordshire, which since 1965 has largely comprised the administrative area of Greater London, governed by 33 local authorities and the Greater London Authority.
