The Moody Blues - the story in your eyes, 1971

"Still not convinced the Moodies can rock? Cue up this riffy Hayward number from the band's typically oh-so-mellow Mellotron days. No doubt on the strength of that guitar-focused attitude, "The Story in Your Eyes" soared to No. 23 in America – likely before anyone noticed its thrillingly weird coda." 

Such a great song!
