Sue Lawley's castaway in Desert Island Discs this week is jockey Bob Champion - a man who, against all the odds, fought back after he was diagnosed as having cancer to win one of the most coveted prizes in his field - in 1981 he rode Aldaniti to a stunning victory in the Grand National. He'll be talking about his passion for riding, his fight against his illness and the two children who, contrary to all medical predictions, he has since fathered.
