The Nelson Mandela 70th birthday tribute concert held at Wembley Stadium, London on 11 June 1988, was attended by a capacity audience of 92,000 and broadcast by the BBC to 63 countries. It was organised by the AAM with the support of Artists Against Apartheid. The concert was part of the AAM’s Nelson Mandela: Freedom at 70 campaign. Mandela became a household name and a public opinion poll found that 70% of people in Britain supported the call for his release.
