Overview
"I'd Like to Teach the World to Sing (In Perfect Harmony)" is a pop song that originated as "True Love and Apple Pie", by British hit songwriters Roger Cook and Roger Greenaway, and sung by Susan Shirley.
The lyrics were rewritten by the songwriters, together with US advertising executive Bill Backer and US songwriter Billy Davis, as a jingle for The Coca-Cola Company's advertising agency, McCann Erickson, to become "Buy the World a Coke" in the 1971 "Hilltop" television commercial for Coca-Cola and sung by the Hillside Singers. "Buy the World a Coke" was produced by Billy Davis and portrayed a positive message of hope and love, featuring a multicultural collection of teenagers on top of a hill appearing to sing the song.
The popularity of the jingle led to its being re-recorded in two versions: one by the New Seekers and another by the Hillside Singers, as a full-length song, dropping references to Coca-Cola. The song became a hit record in the US and the UK.
Origins
The idea originally came to Bill Backer, an advertising executive working for McCann Erickson, the agency responsible for Coca-Cola. Backer, Roger Cook and Billy Davis were delayed at Shannon Airport in Ireland. After a forced layover with many hot tempers, they noticed their fellow travelers the next morning were talking and joking while drinking Coca-Cola. Backer wrote the line "I'd like to buy the world a Coke" on a napkin and shared it with Cook and Roger Greenaway.
