I know people who knew him when he was young and he was always that way. Met him once in a bookshop when we both went for the same book. We chatted about the Electric circus a Manchester venue that had just been pulled down. Ordinary conversation with an interesting bloke. . Not once did he try to bum me.

Then their own entourage, PR machine and hangers-on validate their own self-belief and convince them that they have a valid answer to everything and everyone should hang on to their every utterance.
Then quite suddenly they're second billing on the chicken-in-a-basket circuit.
