Ah, the old eternal philosophical question: If a fight is locked away in Cuba and no-one has seen it, does it exist at all?
Yeah, the second Robinson-Gavilan fight would be great just to see how much better prime Robinson was than the Kid.
There are two fights from the 60's that were filmed, but apparently no longer exist. I would choose Africa's greatest, Tiger v Frank DePaula at MSG. Liston v Folley, is the other, but Tiger is my choice as I have to pick one.
Beat me to it, was filmed though. It was shown in Britain, Australia, Mexico, Venezuela and probably California. The Castillo Cruz 2 fight is in full on YouTube and was the chief support so where is it!!!
