"Thank God for that. You can shut them, say, ‘Hold on a moment.’ You play God to it. But who has ever torn himself from the claw that encloses you when you drop a seed in a TV parlour?

But with all my knowledge and scepticism, I have never been able to argue with a one-hundred-piece symphony orchestra, full colour, three dimensions, and I being in and part of those incredible parlours."
