The Lighthouse Stevensons - documentary about the building of lighthouses in Scotland is a great watch. Available on iPlayer until 14th May.
Caledonia TV have told me that the music is composed by Paul Mounsey specially for the programme. Thus it is not available to buy. There is one piece of music which flows through a lot of the programme that is lovely, in my view.
Did you watch this? If you hear of this music being available, please do post details.
