|Henry Cooper v Cassius Clay - Wembley|
Henry Cooper has returned to Wembley Stadium to promote a new website.
He chatted at length to BBC London's Tom Edwards about his most famous fight at the venue when he knocked Ali down in 1963 just before Ali, then known as Cassius Clay, went on to become world champion.
The referee stopped the bout in the fifth round as Cooper was bleeding profusely above the left eye.
Cooper, 72, is promoting a website called Map My London that aims to create an emotional memory bank for the capital.
The former British, European and Commonwealth champion also talked about the atmosphere at Wembley on that historic night and what is was like to be inside the new stadium.
