There will never be another like this...

If you didn't watch it last night, Parkinson Meets Muhammad Ali is on iPlayer for another 29 days. I'd get on that, if I were you.

Yes, the contrast between 1971 Ali and 1981 Ali is sad, especially with the hindsight of knowing what was to come next (and I'm not just talking about Trevor Berbick). But Ali in 1971 ... what a man. What a character. And what a dream for Parky, in this interview.

Some might say that even the 1974 appearances burn a little less brightly, and they'd probably be right. But oh, to ever burn like this at all.

In the ring, everyone always talks about the incredible achievement of regaining the title at 32, at the Rumble In The Jungle, or the brutality and bravery of the Thriller In Manila. Maybe shaking up the world against Sonny Liston. But if you really want to see Ali box in his pomp, watch his fights with Cleveland Williams and Zora Folley.

Best heavyweight boxer ever? Maybe, maybe not. But greatest of all time? Without a doubt.
