Her most famous recordings — including the chart-topping hits “(You Don’t Know) How Glad I Am,” “Guess Who I Saw Today” and our Song of the Day, “This Girl Is A Woman Now” — bring out the best in her effortless vocalism and narrative flair. Wilson died on December 13, 2018. In this article, we remember her legacy through her music.
