'sepia' Refers to the last shot in the movie Butch Cassidy And The Sundance Kid (1969). Butch Cassidy and the Sundance Kid is a comedy/drama about the friendship and camaraderie between two buddy leads - legendary, turn-of-the-century Western outlaws. In the last shot of this film the two friends run into an ambush they are lured into by bolivian police men, then the film stops and turns to Sepia (a red-brown tone, the colour of the rolls of old movies), to which the title of this song refers. This symbolises that the two characters are not exactly dead, but fade away: the spectator becomes aware that they are movie-characters, not persons existing in reality. (raindrops keep falling on my head appeared on the soundtrack of 'butch cassidy and the sundance kid').
