the Not Going to Play Sun City movement was part of the larger movement in the 80's against Apartheid. There was a lot of activism, especially on College Campuses, for disinvestment from South AFrica and businesses that did business in S. Africa as well a movement to push the United States gov't and other Western govt's to impose sanctions on South Africa in order to push for an end to apartheid and the release of Nelson Mandela.
