 The cost of the tickets was too high for many fans in South America , so the band broadcast the 11 February concert in Chile live on television . Knowing that many people in the country would be watching , they played " Mothers of the Disappeared " in place of " Wake Up Dead Man " . The stadium in which the concert was held had been used as a prison camp by Pinochet 's regime following the coup d 'état . Again it was performed solely by Bono and the Edge against footage of the Madres , and they invited the women to join them on stage a second time . The Madres held up photographs of their children and spoke about them briefly during the performance , an act which received a mixed reception from the audience . Bono made a plea to Pinochet , asking him to " tell these women where are the bones of their children . "
