Each program in the Impact! series puts the spotlight on the songs that have left an indelible mark on the world. Certain songs have come to define the times in which they appeared as they proved to be the catalyst for the transformation of the cultural and political landscape. Most set trends in music, fashion and dance while flouting convention and testing the boundaries of society's accepted moral values.

Besides setting the scene for the release of the song, the programs feature the songs creator(s) and explore its cultural impact and the ways that it changed the course of history. Guests include recording artists, music industry executives, cultural and political pundits and the music fans themselves for whom these songs became their life's soundtrack.

Despite whatever Bob Marley s original intent was for this song, it assumed a bigger meaning; fighting against social oppression and social injustice. I Shot the Sheriff became a direct response to political oppression. It was crucial in defining Marley s role as a political and musical revolutionary. It endeared him to an international audience that was looking for someone to carry the flame of rebellion. By the mid 70s, Bob Marley and reggae music had broken through internationally, but nowhere did its political message and accompanying Rasta image have more impact than in Britain. In the late 70s, reggae and punk would in fact unite under the banner of Rock Against Racism to play concerts to demonstrate solidarity against white supremacist groups. It prompted a sense of respecting cultures; respecting ideas; looking into things politically; looking into where the real issues are throughout the world. The movement reflected the human desire for racial harmony and for a spiritual dimension. Bob Marley s impact in both areas cannot be underestimated. He turned the Rastafari movement into a universal force reaching out to all races. The movement was crystallized in I Shot the Sheriff.
