I've had this song in a drawer for a long time, maybe seven or eight years. Every time I'd do an album, I'd take it out and listen to it, and always liked what it had to say. Plus when Garth came in and sang on it, that made it really special.
After I've sent my revised draft to my agent and editor, they suggest more improvement sand again, this revision phase can take anywhere from a few hours to a few months.
