Extremely Cool New Tolkien Recording Found

From a dinner in the Netherlands hosted for him in March 1958.
At the start of the speech Tolkien is indeed full of high-spirits and cracks jokes in a way that we’ve never heard him do before. Rather than the ultra-serious Oxford don whom most of us know from his scanty recordings, we get Tolkien-as-Bilbo, right out of the chapter “A Long-expected Party.” He even makes reference to that famous eleventy-first birthday, for Tolkien’s oration was intended as a parody of Bilbo’s farewell speech. The author’s merry voice, with its brusque and rich accent, dances around your head like a hobbit drinking song. For the Professor, it was said by one of his former students, “Could turn a lecture room into a mead hall.”
Tolkien thanked the assembled “hobbits” for giving him the greatest party of his life. He spoke very modestly about The Lord of the Rings calling it “A poor thing, but my own.” He couldn’t believe that the people there would want to hear an after-dinner autobiography. So he jumped right into explaining the construction of his great narrative work, stating that the One Ring is a mere mechanism that “sets the clock ticking fast.” And then he quite plainly spells out what the books are about–something he only alluded to once in a letter, but is incontrovertible in this speech. (If you want to know exactly what he says you’ll just have to listen for yourself!)
At one point he read a poem in Elvish, joking that hobbits were always terrified when someone threatened to recite poetry at a party. He prefaced the poem by saying it was almost twenty years to the day since he had started working on The Lord of the Rings. His mellifluous voice makes the imaginary language come alive, like sinuous silvery mithril script etched in the mind’s eye:
Twenty years
