Anne Briggs

Anne Briggs (born 29 September 1944) is an English folk singer. Although she traveled widely in the 1960s and early 1970s, appearing at folk clubs and venues in England and Ireland, she never aspired to commercial success or to achieve widespread public acknowledgment of her music. However, she was a highly influential figure in the English folk music revival, being a source of songs and musical inspiration for others such as A.L. Lloyd, Bert Jansch, Jimmy Page, The Watersons, June Tabor, Sandy Denny and Maddy Prior.
