I'm suggesting that he must have made some notes beforehand, just in case, because if all that really was off the cuff, the chap has a quite extraordinary capacity for creative thinking under pressure. Even if what he created was some clichéd, turgid nonsense, it weas remarkable to find it within and spew it our comprehensibly.
There was one particularly cringeworthy moment when he said something along the lines of 'they said it could happen, it is happening, right here, right now'...
Or some such. It was so cringe my short term memory has subsequently blocked it out.
for 5 minutes than listen to him roll off all that cringey ****.
