I apologize if this is off topic.
I think most of his listeners would agree with me that Gian-Carlo Rota had a wonderful style of lecture delivery. I have heard him lecture, both as an undergraduate lecturer and a technical colloquium speaker.
My efforts to find any video recordings of Rota delivering a mathematical lecture have failed. Thus my question, does anyone know of any such videos? MIT Archives might have some, possibly, but I am not based in North America so contacting them has proved to be difficult.
