Songs

Volume II of Robert Heinlein's Future History, The Green Hills Of Earth, is named after a song written and sung by Heinlein's character, Rhysling, the Blind Singer of the Spaceways. Rhysling expresses the nostalgia of spacemen who have traveled into the Solar System.

Volume II of Poul Anderson's Harvest of Stars Tetralogy, The Stars Are Also Fire, is named from a line in a song (34, p. 459) written by Verdea, a Lunarian daughter of Dagny Beynac, the "Mother of the Moon." Verdea expresses Lunarian defiance of the Terrestrial Federation.

Volume I of the Future History is The Man Who Sold The Moon.

Reading Anderson's later future histories, we still hear the echoes of Robert Heinlein.
