"Peckinpah was apt to strange behaviour and moods," Kristofferson recalled. "and I spent a lot of time chatting in our trailers and I told him about my friend Willie Nelson. I asked Bob, 'Why isn't Willie famous? He's a genius.' So, the next day, Bob calls Willie up and gets him to come down to the set, and he made him play his old Martin guitar for ten hours straight. They ended up doing all these old Django Reinhardt tunes. It was fabulous."
