Book excerpt: Richard Burton: star. The roaring boy from the Welsh coal valleys who came to sport on the banks of the old Nile, playing great Antony to Elizabeth Taylor's Cleopatra. From the West End to Hollywood, from Camelot to Shakespeare, he drank, dazzled and despaired, playing out his life on the public stage. But there was another, quieter, off-stage Richard Burton, a face hidden from the multitude. Melvyn Bragg, allowed free access to the never-before-revealed Burton private notebooks, and with the cooperation of friends who have never spoken about him before, has brought together the private and public sides for the first time. Rich is the complete Richard Burton: a revelation.
