A Nation Once Again was voted the world's most popular song according to a BBC World Service global poll of listeners, ahead of "Vande Mataram", the national song of India. Davis copied the melody for the chorus from the second movement of Mozart's clarinet concerto. The lyrics use a simple ABABCDCD rhyme scheme, with verses of eight lines, and alternating lines of iambic tetrameter and iambic trimeter. Davis describes how he learned of ancient fighters for freedom as a boy — the three hundred Spartans who fought at the Battle of Thermopylae. The "three men" may refer to Horatius Cocles and his two companions
If I Forget Thee, Oh Earth If I Forget Thee, Oh Earth "If I Forget Thee, O Earth" is a science fiction short story by English writer Arthur C. Clarke and first published in 1951 in the magazine "Future SF". It was subsequently published as part of a short story collection in "Expedition to Earth" (1953). The title is taken from Psalm 137:5—"If I forget thee, O Jerusalem"—which consists of the writer lamenting over the destruction of Jerusalem by the Babylonian army. The themes in the story exploit the anxieties prevalent at the time regarding nuclear warfare. The work was well received. "Christian Science Monitor" reviewer
