This traditional Northern English ballad tells the story of a series of impossible tasks given to a former lover. The lyrics, which often include the refrain "parsley, sage, rosemary and thyme," describe a back-and-forth challenge between two individuals. One sets an impossible task, and the other responds with an equally unattainable demand. The version popularized by Simon & Garfunkel in 1966 takes on a reflective, almost haunting quality, with its counterpoint arrangement. At its heart, the song explores the lingering connection and unspoken challenges between past lovers.
