Banjo is the humblest of musical instruments. And Pete Seeger was the gentlest of of Americans. But together they shook the world's most powerful empire for almost a century through the sheer power of their song. The folk music legend died in peace at the beginning of the new year at the age of ninety four and his banjo only a little younger has fallen silent. But their music lives on in defiant optimism of a better life for everybody on our planet.
