I was at a do years ago and D'allalgio was the guest speaker. He told a story of how when he first started playing first class Rugby, as a lad, he was at a line out opposite Richards, who promptly elbowed in him the gob as they went up for the ball. He was told by the coaches that he had to hit Richards back asap, or he'd get no respect. Obviously, he was a tad skeptical about this but did as he was advised and lamped Richards at the first opportunity - Richards just smiled and nodded at him - he'd been expecting it!
