WHAT on earth is Sinéad O'Connor doing at the Greenbelt Festival? I keep getting asked that question by people who know that I have met and interviewed her many times, but who think she must be crazy because of the things she does.
Tattooing her face, for example; posting wildly personal comments online, advertising for a man in the Irish press, getting married (for the fourth time) in Las Vegas . . . and splitting up a week later; being ordained in an independent Catholic denomination; ripping up a picture of the Pope live on American prime-time television - she makes headlines as easily as breathing.
