In the early '90s (perhaps 1991 or 1992) I remember seeing a TV
commercial promoting tourism in Massachusetts.  The only things I
remember about the visuals are a shot of a wheat field blowing in the
wind, and a big title reading "MASSACHUSETTS" at the end.  What I am
interested in, though, is the music that was used in the ad.  It was a
very haunting instrumental tune with "big orchestra" strings, an
African-sounding choir and kind of a pop drum beat.  Can anyone tell
me the title/composer of this piece of music, and where I might be
able to purchase a copy of it?
