"I'd Like to Teach the World to Sing (In Perfect Harmony)" is a pop song that originated as the jingle "True Love and Apple Pie", by British hit songwriters Roger Cook and Roger Greenaway, and sung by Susan Shirley. The popularity of the jingle led to it 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.
