In a charming appearance on The Late Show with Stephen Colbert, rock legend Robert Plant shared that his Led Zeppelin bandmates had no idea he was weaving J.R.R. Tolkien references into the band’s lyrics. Chatting with Colbert, Plant reflected on his youth spent in the same Welsh countryside where Tolkien once lived, revealing that those mystical landscapes and epic tales seeped into his songwriting for songs like “Ramble On” and “The Battle of Evermore.” As he put it with a smile, his bandmates were blissfully unaware of the Middle-earth magic behind the music. Plant’s latest album ‘Saving Grace’ is out everywhere now.
