1969: Led Zeppelin - Ramble On

 

Ahha, danke Wikipedia:

The song's lyrics were heavily influenced by The Lord of the Rings by J.R.R. Tolkien.^[1] The opening line ("Leaves are falling all around") is probably a paraphrase of the opening line of Tolkien's poem "Namárië". The poem may also be the inspiration for the entire first verse.
The Tolkien references later in the song refer to the adventures of either Frodo Baggins as he travels to Mordor, or that of Aragorn as he has to choose between staying with his love Arwen (Elrond's daughter) or going to destroy the Ring in Mordor:

Mine's a tale that can't be told,
My freedom I hold dear;
How years ago in days of old
When magic filled the air,
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.
(Ramble On, Led Zeppelin)
