They wrote that during the show that the singer said the smoke machines had affected his voice. “Bono said that he’s not quite sure what’s happened at the end of Red Flag Day. He’s clearing his throat. ‘I think it’s the smoke. I can promise you I have not been talking, but this is like a giant cigar - I’ve lost my voice and I don’t know what to do’,” the fan site tweeted. The singer reportedly left the stage after attempting to sing “Beautiful Day”.
