"

During the 1970s, Lightfoot's songs covered a wide range of subjects, including "Don Quixote", referencing Cervantes' famous literary character, "Ode to Big Blue", about the widespread killing of whales, "Carefree Highway", about the freedom of the open road, "Protocol", about the futility of war, and "Alberta Bound", inspired by a lonely teenaged girl he met on a bus while travelling to Calgary in 1971.[citation needed]
