Thanks once again for your efforts in providing this.
I am old enough to recall when the Clyde steamers called at Innellan, though never disembarked there, and was familiar with the story of George Matheson. Indeed, I chose that particular hymn to be played while waiting for the commital at the crematorium following my mother's funeral in Church - partly because the tune is St Margaret, and that was her first name. She would not have claimed to be a saint, but to my mind got as near as most folks can.
I must say that I do like your minister's delivery: clear and unpretentious seems an ideal recipe and he follows it perfectly.
