An exploration into the enduring appeal of the Dire Straits classic, Brothers in Arms.

Although thought to have been written by Mark Knopfler in response to the Falklands war in the mid 1980's, it's a piece that people now associate with many other conflicts; military, personal and social.

Snuffy Walden, music director of the hit American TV show, The West Wing, talks about how the series writer, Aaron Sorkin insisted on it being used in its entirety during a crucial episode.
