The effect that a simple song can have on the world is real and tangible. The power of words, whether sung or spoken, can change minds and can move people to action. Great songs can crystallise a moment in time, or encapsulate transition in culture. They influence events and alter the course of history. The ten songs in this book have changed the way people think and act and in so doing have changed the world. Music author June Skinner Sawyers explores the social and cultural legacy of each song.
