Bilbo's Last Song by J. R. R. Tolkien. It was given by Tolkien as a gift to his secretary Joy Hill in 1966. Although it was never published in the author's lifetime, it has been published in text form and with music several times since Tolkien's death in 1973.
still round the corner there may wait a new road or a secret gate and though i oft have passed them by a day will come at last when i shall take the hidden paths that run west of the moon, east of the sun. - j.r.r. tolkien
