I'd Like to Teach the World to Sing (In Perfect Harmony) is sung by young Hayley and Stan when Francine shows them they used to be friends in Stannie Get Your Gun. The pop song 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.
