The Battle of Evermore - Mandolin / Guitar Mix from Headley Grange

Robert Plant wrote the words to this acoustic song after reading a book on Scottish history. The lyrics are about the everlasting battle between night and day, which can also be interpreted as the battle between good and evil.

This is the only song Zeppelin ever recorded with a guest vocalist. Robert Plant felt he needed another voice to tell the story that plays out in the song, so Sandy Denny from Fairport Convention was brought in. Her vocals represent the people as the town crier, while Plant's voice is the narrator. Fairport Convention was a British folk group Zeppelin shared a bill with in 1970. This collaboration with Sandy Denny marked the first time Robert Plant did a duet with a woman. In later years, he had tremendous success singing with Alison Krauss; their 2007 album Raising Sand won a Grammy award for Album of the Year.

Sandy Denny was given a symbol on the album sleeve - three pyramids - to thank her. The four members of Led Zeppelin each designed their own symbols for the album. Denny died in 1978 from a brain hemorrhage resulting from a fall down the stairs.
