Should the mere mention of National Have a Coke Day on May 8 inspire a spontaneous burst into song, you're certainly not alone. Penned in 1971, the song "I'd Like To Teach The World To Sing (In Perfect Harmony)" has been recorded countless times. This musical creation was featured in the iconic hilltop Coke commercial, where the lyrics "I'd like to buy the world a Coke" and "It's the real thing" were added, creating a poignant and enduring fusion of Coca-Cola, peace, and harmony. This resonated deeply during the "flower power" era and continues to be sung today.
