Hi, Wldcare - pop songs like that are best found in places like The International Lyrics Server. "Fields of Gold" are what are found almost everywhere here in California, from May to December. That's why they call us the "Golden State." Of course, since I'm not a native Californian, I know the "gold" is really "brown." Maybe Sting spent too much time in California, or listened to too may travel agents' glowing descriptions of California.
Aw, I shouldn't be so cynical. It really is a pretty song, even if it isn't a folk song. I think, though, that Sting left the type of gold up to the listener's imagination - although some of the fields are specifically defined as barley.
