All things Cash continue to fascinate us, even though the famous pair, June and Johnny, have been dead for years. The recent film Walk the Line opened the door into their life a crack, but focused mostly on John (and may have been guilty at times of taking the rose-colored view). Johnny's artistic temperament and drug use are well-documented, but what of June? She was talented, kind, tolerant, and supportive... but we've each got a dark side, and she was no exception. June and Johnny's son John Carter has written a book about her life, a task he seems uniquely qualified to take on... but it makes me wonder about children documenting the lives of their parents. Is it possible to do so without an agenda? And aren't there some things about your parents you'd just rather stay in the dark about?
