But I got a phone call from Bono in 1985 and, as you know, he's a great singer, but he's a magnificent hustler, and -- (Laughter) -- a very hard guy to say no to, and he was saying, you know, just after I'd done the Biko song, we're going to do a tour for Amnesty, you have to be on it, and really that was the first time that I'd been out and started meeting people who'd watched their family being shot in front of them, who'd had a partner thrown out of an airplane into an ocean, and suddenly this world of human rights arrived in my world, and I couldn't really walk away in quite the same way as before.
