The cultural boycott against South Africa was lifted in 1991, five years after "Graceland"'s release. At the invitation of anti-apartheid activist Nelson Mandela and with the African National Congress's support, Simon and his band played five shows, beginning at Ellis Park Stadium in Johannesburg. Before the first concert, hand grenades were thrown into the office of promoter Attie van Wyk, who had booked Simon for the shows. The office was destroyed and no one was hurt. A sect of the militant Azanian People's Organisation (AZAPO) claimed responsibility for the attack.
