Diane Louise Jordan explores Cornwall where she uncovers the secret life of seals, meets skateboarding surfers, walks in the footsteps of Cornwall's patron saint and makes sure that her visit to a Cornish tin mine goes with a bang. Truro Cathedral is the stunning setting for hymns including O God, Our Help in Ages Past; Lord Of Beauty, Thine the Splendour; and Christ Triumphant, Ever Reigning. With music from Hayley Westenra, Daniel Boys and Truro Cathedral Choir.
