The most difficult scene was the paragraph where, on the mountain, Ennis holds Jack and rocks back and forth, humming, the moment mixed with childhood loss and his refusal to admit he was holding a man. This paragraph took forever to get right, and I played Charlie Haden's and Pat Metheny's Spiritual, from their album Beyond the Missouri Sky (short stories) uncountable times, trying to get the words. I was trying to write the inchoate feelings of Jack and Ennis, the sad impossibility of their liaison, which for me was expressed in that music. To this day, I cannot hear that track without Jack and Ennis appearing before me. Annie Proulx.
