Guitarist John Nolan's son, John jr., can be heard singing the chorus in the background at the end of the song. Vocalist Adam Lazzara explained the story behind the youngster's contribution to Radio.com
"He would drive around in his car listening to the demos, and a lot of time his song would be in the car with him… so his son got pretty familiar with the songs. There was one night when he went to put him to bed and so he put him in his room and he closed the door and he was walking by his room five minutes later and heard him singing so he pulled out the voice recorder on his phone and held it to the crack in the door.
So it's his son lying in bed singing the chorus of that song. He played it for us the next day and we were like, alright, that's got to be at the end of the song!"
