The singer and fiddle player Lisa Knapp takes Matthew to the south London borough of Tooting where she was born and brought up. She performs songs with links to the area and tells how she stumbled across the Tooting Tragedy – a story of neglect and ill treatment at a local children’s home in Victorian times that led to hundreds of deaths and caused an outcry led by Charles Dickens. Lisa uncovered a haunting ballad about the story and sings it in the graveyard where many of the children are buried.
