Pictures of Bands On Stage during the 1985 Live Aid Concert at Wembley Stadium

On July 13, 1985, at Wembley Stadium in London, Prince Charles and Princess Diana officially open Live Aid, a worldwide rock concert organized to raise money for the relief of famine-stricken Africans.

Organized in just 10 weeks, Live Aid was staged on Saturday, July 13, 1985. More than 75 acts performed, including Elton John, Madonna, Santana, Run DMC, Sade, Sting, Bryan Adams, the Beach Boys, Mick Jagger, David Bowie, Queen, Duran Duran, U2, the Who, Tom Petty, Neil Young, and Eric Clapton. The majority of these artists performed at either Wembley Stadium in London, where a crowd of 70,000 turned out, or at Philadelphia's JFK Stadium, where 100,000 watched. Thirteen satellites beamed a live television broadcast of the event to more than one billion viewers in 110 countries. More than 40 of these nations held telethons for African famine relief during the broadcast.
