Edwards had a country-flavored folk hit that year called "Sunshine." It was a gold-record smash, in heavy rotation on AM radio back then; the song brought hope and optimism during the bleakest moments of the Vietnam era. Edwards has since supported Emmylou Harris, Don McLean, and B.B. King, hosted a PBS travel series, and produced folksinger Cheryl Wheeler.
By all accounts, "Sunshine" was the highlight of the reclusive Edwards' modest career. If the song still doesn't ring a bell, consult your copy of the Will Ferrell movie, Anchorman. That just might help jog your memory.
