What was the name of Queen's 1992 tribute concert?

Queen’s 1992 tribute concert was called The Freddie Mercury Tribute Concert.

The full event title was The Freddie Mercury Tribute Concert for AIDS Awareness. It took place at Wembley Stadium in London on 20 April 1992, several months after Freddie Mercury died from AIDS-related complications on 24 November 1991. Queen’s surviving members—Brian May, Roger Taylor and John Deacon—performed with a large group of guest musicians.

The concert was both a memorial and a benefit event. Performers included Metallica, Guns N’ Roses, Def Leppard, Extreme, David Bowie, Annie Lennox, Elton John, George Michael, Robert Plant, Seal and Liza Minnelli. The show ended with Queen and guest performers in a series of songs associated with Mercury and the band.

It was also known as A Concert for Life, which explains why that phrase sometimes appears in summaries or archival material. The event was broadcast internationally and attracted an estimated television audience of about one billion people. Proceeds helped establish the Mercury Phoenix Trust, a charity focused on HIV/AIDS awareness and prevention.
