It was producer John Congleton who proposed including a children's choir on "We All Die Young."
"When I suggested the song should have a call and response," lead vocalist Colin Meloy told UK newspaper The Sun, "John just said, 'Well it'll be a kids' choir, right?'"
He added: "Maybe that idea had already occurred to me but I was too shy to mention it? Maybe I thought everybody would think I was a sicko? But John was sicko enough to suggest it and have us go along with it."
Meloy continued: "We used band members' kids and their friends, maybe ten in total, and they really took to it! Kids love that stuff. They can get very dark."
