The songs "The Battle Of Evermore" and "Ramble On" by Led Zeppelin have references to Lord Of the Rings.
The Battle Of Evermore
The pain of war cannot exceed the woe of aftermath,
The drums will shake the castle wall,
The ring wraiths ride in black, ride on.
Ramble On
T'was in the darkest depths of Mordor, I met a girl so fair.
But Gollum, and the evil one crept up and slipped away with her, her, her....yeah.
I was reading this article
“In addition,” Tolkien wrote, “in a house three doors away dwells a member of Group. On days when it falls to his turn to have a practice session the noise is a group of young men who are evidently aiming to turn themselves into a Beatle indescribable.”
I understand he had reasons for not liking Beatles, my question is how did Tolkien react to the references to LOTR in work of Led Zeppelin, was he even aware of the band?
