Good watch. I always find Ali to be almost coy in 1970 before he re-claimed his throne. He's the same in his first interview with Parkinson in '71 after losing to Frazier. I like how Ali cuts Cavett off in the first part, underlining the fact he's not making a religious point.
utube poster said there was only 2 mins left of the show and cavett did most of the talking +end credits so nothing to miss on ali he said. interesting he said he would never fight frazier and was content to never box again.
Muhammad's most famous Parkinson interview was the late 1974 one. My favourite one though,was the one you mentioned. October 1971.
