The song starts and the viewer is met with an image of a burning building juxtaposed with soft acoustic guitar so already the audience knows that it will be, not that emotional but also not the happiest of songs. When the vocals kick in with 'I met my love', a scene from Trainspotting with Tommy and Lizzy together; followed by scenes of soldiers walking through the streets of Ireland carrying guns. Then chop ins and outs of the chase scene from the beginning of Trainspotting with more soldiers in Ireland. This then builds upto the chorus 'dirty old town, dirty old town' in which scenes of heroin use will be shown. This kind of rhythm will continue throughout the song (not the same scenes obviously) culminating in the final chorus in which more drug scenes will be shown and finally the end scene to Trainspotting where the protagonist walks into the distance.
I wasn't worried at all using such an iconic film to cut and de-glamorize for a music video, quite the opposite. I thought that being cliché in itself would be ironic choosing between such cult films as: A Clockwork Orange, Trainspotting, Requiem For A Dream and Get Carter (1971 version ofcourse).
