Here's an excerpt from an interview with the late Johnny Cash. It's not excitingly revelatory, really, but it's refreshing to hear how down to earth Cash is. He denies being a hero or icon, denies being brave, and just plain keeps it real. I may be giving him too much credit, but I feel like his humble answers are heavily influenced by his faith and the rough times he endured (many as consequences of his own choices).
WARNING: Cash does drop an "S bomb." So be careful little ears what you hear.
