I've told this story on here before, but hey-ho. I saw Paul Simon live a couple of years ago. When it came to the famous bass-fill Bakithi Kumalo, clearly asleep at the wheel, utterly ballsed it up. He and the whole band just roared laughing and carried on. Now that's the spirit. Yes we're professionals and we want to do our best, but we're also human and nobody dies if there's the occasional cock-up.
