QED : The Shape Of The Nation music

[nuneatonlad]

In 1988 the BBC aired an episode of the programme QED : The Shape Of The Nation where a RAF Hawk aircraft flew around the British coast and filmed it. This was an extended version of QED : Round Britain Whizz shown 2 years earlier.
I'm interested in the music from the Scotland part. Some of it sounds classical and there is a couple of tracks sung in Gaelic which I would love to know some details of as I can't even write the lyrics down to search.There were no musical credits at all.
Fortunately the whole thing was posted on Youtube in parts which I've listed with links and approximate time the music is heard
