"The Hero" is a Scottish piece originally written by James Scott Skinner in 1903, as "Hector the Hero". "She Moves Through the Fair" is a traditional Irish song, the melody of which had been used by Simple Minds for "Belfast Child" in 1989. "Women of Ireland", although credited as a traditional song, is not: the main theme is a melody written by Irish composer Seán Ó Riada as a musical setting of the poem "Mná na hÉireann", written by Peadar Ó Doirnín; Oldfield's rendition also includes an interpolation of the fourth movement ("Sarabande") of George Frideric Handel's Keyboard suite in D minor, popularised by its use by Stanley Kubrick in his 1975 film "Barry Lyndon", where Ó Riada's tune also appears (Oldfield's "Women of Ireland" was reportedly inspired by the coupling of both pieces in the film). "Dark Island" is a Scottish instrumental and song; the original music was written by Iain Maclachlan as Dr. Mackay's Farewell to Creagorry in 1958. Later used as the theme to a 1962 BBC TV series and re-titled for the series. A set of words were later written by David Silver in 1963. Another well known set of words were also set to a variation of the tune in 1963, by Stewart Ross. "Flowers of the Forest" is a traditional Scottish song, a lament for the defeat at Flodden in 1513. "The Song of the Sun" is composed by Bieito Romero from Celtic band Luar na Lubre. Its original title is "O son do ar" ("The sound of the air").
