I'd like to teach the world to sing (in perfect harmony)

I woke up this morning thinking about this famous song who's lyrics begin with, "I'd like to build the world a home and furnish it with love..." The Coke ad version is credited with making Coke the #1 soft drink in North America and the "Coke removed version" went to #7 in the US pop charts and #1 in the UK and Japan.
