"Earth Anthem" by The Turtles, album: The Turtles Present the Battle of the Bands (1968)

And we are but an island in an ocean
This is our home, third from the sun
Let it be evergreen, let it be evergreen

And we are but an island in an ocean
This is our home, third from the sun
God, Keep it evergreen
To keep it evergreen I would lay my life down

And we are but an island in an ocean
This is our home, third from the sun
Let it be evergreen, let it be evergreen

A request for keeping our planet evergreen.
