Jonathan Freedland on Jimmy Savile, in today's Guardian:
Once again reality outstrips the imagination. Now we see that even the most gifted weavers of children's nightmares... made the same basic error. Their creations... advertised their evil, signalling it from a thousand paces. They were villains who never posed as anything else. Now we know those authors missed a trick. For how much more terrifying is the evildoer who pretends to be good – the devil who tries, and succeeds, in passing himself off as a saint?
Well, here's somebody with the necessary imagination - the one and only Bob, singing: 'You know sometimes Satan comes as a man of peace'. The song also contains the lines, 'Nobody can see through him / No, not even the Chief of Police', and 'He's a great humanitarian, he's a great philanthropist'.
