I do not suppose there is a transcript? I'll offer the obligatory curmudgeonly purist Tolkien fan opinion, while I'm here: Tolkien hated World War I; it drove him to despair for his fellow man, so he spent much of it writing the Fall of Gondolin and the Lay of Leithian (in the trenches and later, while recovering from wounds). If given the choice, I suspect he would have removed the war from all summaries of his life extant. He would be deeply uncomfortable with any depictions of himself as a hero, patriot, so on. He even, I speculate, would reject the hypothesis that the Great War somehow shaped his mistrustful beliefs about the machinery of progress -- because even without it, he would have arrived at those conclusions, and to point to so obvious a cause cheapens their magnitude. Anyway. I haven't the faintest what the video actually says. If there's no transcript I may watch a bit.
Well, they pronounce his name the British way -- wrong -- but this is on the whole very, very apt. I wonder if Christopher was consulted. I've been reading Wodehouse so I'm in a wonderful mood anyway. PS: The Garth book is recommended by the only person I trust on the matter.
