The moment of high drama comes from Sinead O'Connor, who had planned to sing "I Believe In You" but, having torn up a photograph of the Pope on Saturday Night Live while performing Bob Marley's "War" two weeks earlier, is received with mixed cheers and boos, the sounds of disapproval intensifying as she stands there in silence before responding by spitting out the lines of "War". Kris Kristofferson, having introduced her as "an artist whose name is synonymous with courage", leads her gently away.
