On another thought though, I was a taught a tune years ago called Lochbroom. Its in the Patrick MacDonald collection, but I dont imagine it could ever be used for psalm singing.
She did advise however that you contact the Free Church in Ullapool and ask them. Theyre lovely folk up there so will surely help you out.

I have been asked by the minister in the "Fishermen's Church" in Eyemouth if I can source the music to the tune Loch Broom. He is looking to use it to Psalm 107 (They that go down to the sea in ships) at a service to commemorate the Eyemouth fishing disaster of 1881. I notice that you managed to source a sol-fa version of the tune. Would it be possible to get a copy of this and I will transcribe it into staff notation. If it would be of use to you I would send you back a copy of the staff version.
