This hillside hit of the 1970s has its roots as a Coca-Cola commercial. The positive song of hope was performed by a group of radiant, multicultural teenagers on top of a hill. Their message was of peace and love, shining brightly around the Coca-Cola brand. Lyrics include, “I’d like to buy the world a Coke” and “It’s the real thing,” Coke’s marketing theme at the time. It was so popular The New Seekers and The Hillside Singers recorded a full-length version of the song, dropping mention of Coke, and it became a hit!
