"If I had a hammer, I'd hammer in the morning I'd hammer in the evening, All over this land. I'd hammer out danger, I'd hammer out a warning, I'd hammer out love between my brothers and my sisters, All over this land... Well I got a hammer, And I got a bell, And I got a song to sing, all over this land. It's the hammer of Justice, It's the bell of Freedom, It's the song about Love between my brothers and my sisters, All over this land."
