Much like Santa Claus, Woodstock, Adolf Hitler, and the Enchantment Under the Sea Dance in 1955, this song sits at a major focal point in space-time. It had to be written. More than once. I have a hunch that we will find other versions of it scattered throughout the local cosmic continuum, including all of humanity's major cultural junctions, such as Starbucks, your mom's house, and Easter Island.
