In a special edition folk-rock giants Maddy Prior, Simon Nicol, Ashley Hutchings, Jerry Donahue, Jacqui McShee and Judy Collins pay tribute to the late Sandy Denny, who died nearly 40 years ago but is still regarded as the greatest folk-rock singer of all time. The programme includes archive interviews with Sandy herself and features some of her finest music. Mandy & Nicola will also be putting on their hard hats to take you down The Poldark Mine in Cornwall, in the footsteps of Winston Graham, the man who created the famous series of books now getting a second airing on TV.
