Bryan Magee Interviews John Searle on Wittgenstein

On YouTube there is video of (a very young looking) John Searle discussing the philosophy of Wittgenstein with Bryan Magee. The discussion is approximately 45 minutes long, so it's posted as five clips:

Clip 1
Clip 2
Clip 3
Clip 4
Clip 5

I've watched the first clip, and Searle isn't bad. He does confuse picturing and mirroring, and he holds that in the TLP the basic unit of meaning (broadly understood) is the sentence (this is Ryle's view, and Searle was Ryle's student; of course, it's also Diamond and Conant's view). But his explanation of the Tractarian view of negation is pretty good.
