"I'd Like to Teach the World to Sing (In Perfect Harmony)" is a pop song which originated as a jingle in the groundbreaking 1971 "Hilltop" television commercial for Coca-Cola. The song, produced by Billy Davis and performed by The New Seekers, portrayed a positive message of hope and love sung by a multicultural collection of teenagers on the top of a hill. It originally included line "I'd like to buy the world a Coke" and repeated "It's the real thing" as Coca-Cola's marketing theme at the time. It was so popular it was re-recorded by The New Seekers and The Hillside Singers as a full-length song, dropping references to Coca-Cola, and became a hit record. The version by The New Seekers reached #7 in the United States. The Hillside Singers' version was released as a successful single the same year; it reached #13 on the Billboard Hot 100 and #5 on Billboard's Adult Contemporary chart.
