I found a recording of JRR Tolkien himself speaking the poem/song Namarie that Galadriel sang.
Christopher Tolkien about his father and the writing of the Silmarillion.
King Azaghal was I, Lord of Belegost.
Fought the father of dragons at great cost,
During the Battle of Unnumbered Tears,
Nearly killed the Great Worm of our fears,
I Stabbed my knife into Dread Glaurung,
Could be worse, I could be dragon dung.
Hey dol! merry dol! ring a dong dillo!Ring a dong! hop along! fal lal the willow!Tom Bom, Jolly Tom, Tom Bombadillo!
Utúlie'n aurë! Aiya Eldalië ar Atanatári, utúlie'n aurë! Auta i lómë! Aurë entuluva!
