There's a tremble in Cash's voice on the cover. Which makes the lyrics much more impact full. It's full of pain and regret, from a man at the end of his days. Trent Reznor may have written it, but in my eyes it's Johnny's song now. Plus the music video fits his version so much better. The shaky hands, the sad eyes. Reminiscing about the past. It all just fits so well together. It was the perfect cover all around.
