On April 20th 1992, Roger Taylor, Brian May and John Deacon, the surviving members of Queen, took to the stage at Wembley Stadium for the start of one of the biggest events in rock history, which the band had organised to pay tribute to their former colleague -- the incomparable Freddie Mercury. Queen were joined by some of the greatest musical talent in the world to celebrate Freddie's life and work and to increase public awareness of AIDS, the disease that had prematurely ended his life the previous year. As well as being great entertainment, the concert raised a huge and still growing sum of money for the Mercury Phoenix Trust, a charity formed at the time whose charter is the relief of suffering from AIDS throughout the world.
