It was the way that the whole thing was set-up: the back-stage interview in which she said that as a single 47 year old she'd never been kissed; the answers she gave to the judges questions before she sang, stating that she wanted to be a professional singer but had never been given the opportunity; and the utter contempt that audience and judges made no effort to conceal. And then she opened her mouth, and I confess that it brought tears to my eyes and yes, I was stunned - what a performance! And actually there was something about it that was so gospel.
If you haven't heard it, then go here and enjoy! When I last looked there were nearly 6 million hits.
