If it weren't for the Led Zeppelin song, Ramble On, I probably never would have read Tolkien's masterpiece, The Hobbit.
Tolkien, J. R. R. The Hobbit, or, There and Back Again. Boston: Houghton Mifflin, 1966.
I don't usually go for fantasy books, but I read The Hobbit in order to learn more about Gollum and the depths of Mordor.

And speaking of Zeppelin, it's also John Paul Jones's birthday! (He's still alive, I think.)
