"We used to wake up in the morning and the mist would be lifting we'd see thousands and thousands of people who'd been walking all night to our food station were we were working. One man — I was standing outside talking to the translator — had this beautiful boy and he was saying to me in Amharic, I think it was, I said I can't understand what he's saying, and this nurse who spoke English and Amharic said to me, he's saying will you take his son. He's saying please take his son, he would be a great son for you. I was looking puzzled and he said, "You must take my son because if you don't take my son, my son will surely die. If you take him he will go back to Ireland and get an education." Probably like the ones we're talking about today. I had to say no, that was the rules there and I walked away from that man, I've never really walked away from it. But I think about that boy and that man and that's when I started this journey that's brought me here into this stadium. Because at that moment I became the worst scourge on God's green earth, a rock star with a cause. Christ! Except it isn't the cause. Seven thousand Africans dying every day of preventable, treatable disease like AIDS? That's not a cause, that's an emergency."
