Book excerpt: From his gold medal at the 1960 Olympic Games to his defeat of Sonny Liston to claim the world heavyweight championship in 1964, the unforgettable 'Thrilla in Manila' against Joe Frazier and the 'Rumble in the Jungle' against George Foreman, 'The Greatest of All Time', Muhammad Ali, has captured the attention of the world. His conversion to Islam, his refusal to serve in the in the Vietnam War ('I ain't got no quarrel with them Vietcong') and his speaking tours in the 1960s have all contributed to his status as one of the most revered sporting figures ever. Here, drawn from books, specialist periodicals, newspapers, college magazines (covering his speaking tours) and the work of major literary figures such as Thomas Hauser is the biggest and best collection ever of writing on 'The Greatest'.
