"I'd Like To Teach the World To Sing (in perfect harmony)" was a jingle for Coca-Cola written by Roger Cook and Roger Greenaway aka David and Jonathan as recording artists. Roger Cook sang this live at a TED presentation in Nashville.

The studio jingle singers decided to call themselves The Hillside Singers in identifying with the commercial and dropped the Coke references on the re-recording. They peaked at thirteen on Billboard's pop chart.

Eve Graham and The New Seekers has a slightly bigger hit than the Hillside Singers peaking in the top ten.
