Frontman Cormac Neeson (from Kerrang! February 21, 2009): "The lyrics are based loosely on a friend of mine that committed suicide back in my school days. In the chorus of the song I'm just trying to understand what goes through a person's mind and why they should take their own life. The night we finished recording it, we were listening back to the bare bones rough mix drinking tequilas and saying that this was a really powerful f—king song."
The lyrics for "Mary, Did You Know?" were written by Christian singer and comedian Mark Lowry, after his pastor asked him to write a Christmas musical for their church. Southern gospel musician Buddy Greene later added music to his words.
