Cover art for Prowl Great Cain lyrics by Mountain Goats, The

During a recent live show, a girl in the audience yelled out "My boyfriend loves you!", to which John replied somewhere along the lines of: "Well, I love him back! Does he still remember that time in Cambodia when I sold him out to the enemy to save my own skin? I still feel bad about that." Then he launched into this song.

Obviously a song about betrayal and guilt, it's just the Cambodia comment adds more context for me.
