The commentary in the fight is kind of matter-of-fact: Mr Van Buyton has never seen, in all his time as champion, such a big foot. When he (Andre) falls, it's monumental. (this after a takedown by Van Buyton) The tree doesn't give up. (this when VB had an arm lock on Andre, before Andre throws him across the ring one-handed straight from the lock).
The whole structure of the fight is showing that Van Buyton has a big technical edge (well, he was champ, Andre was a newb) but that there's just not much he can do with the beast he's trying to tame. Arm lock, leg lock, head lock - each one lasts a bit then ends with Van Buyton launched across the ring one-handed or one-footed. Some more head locks, throat lock, some leg whip flippy flippy stuff. Basically all of it starts with Andre hugely *******phing something, the quicker, lighter, "more skilled" Van Buyton turning it into something, then Andre just overpowering his way out of each.
The commentary isn't that out of hand, really: there's no Jesse Ventura or anything on there. When Van Buyton tries a flying dropkick, Andre barely steps back and there, they are "He didn't move, he didn't move!!!" And that's about as emotionally charged as they get. They try to sell that Van Buyton's moves are doing something, a little, but you'd have to be blind to believe that.
Getting closer to the end, with each of them launching punches, Van Buyton
spearing Andre mid chest with the top of his head (this causes me neck pain just seeing), etc. the commentators start complimenting Van Buyton's courage. It's clear where it's going, as Van Buyton is giving everything and it's doing nothing lasting.
That's it. It wouldn't be out of place as old boxing commentary. Nothing like what you'd see today or even in the 80's on WWF sunday morning television.
