Aside from the Clapton/Kamen soundtrack, Willie Nelson's "The Time of the Preacher", New Model Army's "Christian Militia", and Tom Waits' "16 Shells From A Thirty-Ought-Six" are featured in the series. "Christian Militia" is on the record player when Terry's body is found. Craven listens to "The Time of the Preacher" when he is in Emma's room in the first episode. It later emerges Jedburgh is familiar with the song and both he and Craven sing it on two occasions, the lyrics being significant.
