In this article I start from an understanding of songs as socio-cultural discourses which may also perform a political function. This political function can be reflected in the promotion of particular world-views about given socio-political events and/or in the attempt by the singer to make the audience perform given political actions. To prove this, I will look at the re-contextualization process undergone by a well-known song by U2: “Sunday, Bloody Sunday” (1983).This song was originally written to respond to the violence of the Northern Irish conflict, but it has been later used to react to other socio-political events. By relying on a cognitive approach to the study of songs, this paper tries to answer two questions: i) how can we explain the re-contextualization process undergone by the song and why is it possible? and ii) how is politics embedded with musical performances?
