This video clip, of a Welsh phone-salesman singing Puccini's "Nessun Dorma", is one of the more moving things I've seen. Apparently, he's been an international sensation for more than a year now, so you may already have seen it. If not, it's absolutely worth your time. (Watching Simon Cowell's smirk melt away into incredulity is the least of its pleasures.) I don't know how you can watch it without tearing up.
