I remember hearing him speak. That's definitely him. He spoke without notes, and he had a kind of rambling way of speaking, though it was interesting and easy to listen to.
There is a little ambiguity on the statements about his <maybe> offer of Rhodes scholarship and to Oxford. It sounds to me like he applied for the scholarship and later withdrew his application. Maybe just that process meant that he was automatically accepted to Oxford (with or without the scholarship), but it isn't really clear to me.
