Alfred Mamba was just 12 when boxing great Muhammad Ali descended on Kinshasa, at that time the capital of Zaire, in October 1974 in a bid to regain his heavyweight title.

Mamba watched as his father — a boxing referee — helped carry flags into the arena ahead of the fight between Ali and fellow-American George Foreman in the early hours of Oct. 30.

The memory of the event, better known as The Rumble in the Jungle, has stayed with him for 50 years.
