Revelations is a series of articles looking at turning-points in people's attitudes.
I've had about 45 years of being very disparaging about artists getting involved in anything political, I'd even written a very snotty article in The Guardian , in which I made a very unkind allusion to that 'Free Nelson Mandela' song, saying that it isn't the job of artists to do things like that. The usual stuff people say when they don't know what they're thinking and feel a little bit guilty for not doing anything. The Sahel, for example, where the problem is desertification. Whoever pushes hard enough for their issue or makes the most noise is probably going to make a difference. It's nothing to do with the justice of the issues, the rightness or wrongness.
