Annie Proulx said that the most difficult scene to write was that of Ennis holding Jack and rocking him back and forth, "humming, the moment mixed with childhood loss and his refusal to admit he was holding a man." She was greatly influenced by the music 'Spiritual' by Charlie Haden and Pat Metheny from the album Beyond The Missouri Sky and listened to it countless times in order to get the words right.
