After Freddie Mercury died of AIDS, the three remaining Queen members, Brian May, Roger Taylor and John Deacon, decided to celebrate the life and legacy of their vocalist in a style that he would approve of.
This resulted in the Freddie Mercury Tribute Concert for AIDS Awareness, held on April 20, 1992. It remains the largest concert held in tribute to a deceased musician. The 72,000 tickets for the London Wembley Stadium were sold out within a few hours - even though none of the performers had been revealed--apart from Queen.
It was soon learned, though, that names like Elton, Axl Rose, Robert Plant, George Michael, and David Bowie would be taking the stage.
The show was broadcast in 76 countries. All proceeds were donated to a specially created AIDS charity organisation, the Mercury Phoenix Trust, which is still active today.
