The Nelson Mandela 70th Birthday Tribute was a popular-music concert staged on 11 June 1988 at Wembley Stadium, London, and broadcast to 67 countries and an audience of 600 million. Marking the forthcoming 70th birthday (18 July 1988) of the imprisoned anti-apartheid revolutionary Nelson Mandela, the concert was also referred to as Freedomfest, Free Nelson Mandela Concert and Mandela Day. In the United States, the Fox television network heavily censored the political aspects of the concert. The concert is considered a notable example of anti-apartheid music.
