  ==Background==
  "Jenny of Oldstones" is an adaptation of a song mentioned in George R. R. Martin's fantasy novel series ''A Song of Ice and Fire'', on which ''Game of Thrones'' is based. In the third novel in the series, ''A Storm of Swords'', a character asks for "my Jenny's song" to be performed. Only one line of the song is quoted in the novel itself: "High in the halls of the kings who are gone, Jenny would dance with her ghosts." In the fictional history of the world of ''A Song of Ice and Fire'', the titular Jenny of Oldstones was a commoner whom a prince gave up his inheritance to marry. 
  The song was written by German composer Ramin Djawadi, who composes the music for ''Game of Thrones'', and screenwriters D. B. Weiss and David Benioff, who added lyrics to the fragment written in ''A Song of Ice and Fire'' by Martin. Florence and the Machine's recording of it was produced by American musician Doveman and Florence and the Machine frontwoman Florence Welch. The song is a folk ballad, with influences of Celtic music. Weiss and Benioff reportedly approached Welch in 2012 to record the song "The Rains of Castamere", although she had turned down their request. Following the release of "Jenny of Oldstones", Welch stated in an interview with ''The New York Times'' that this was during her "wild years", when she was "less focused".
  In the episode "A Knight of the Seven Kingdoms", the recording of the song by Welch was played over the closing credits. The song was however first heard performed by Daniel Portman as the character Podrick, who sang a verse in a sequence reminiscent of the scene in ''The Lord of the Rings: The Return of the King'' when Pippin sang "The Edge of Night" before the battle of Minas Tirith. The version sung by Portman is a simplified in its harmonies, while the version by Welch is close to how Djawadi originally wrote it with more chord changes.
