As I was reviewing this message, I realized my bad typing had snagged me again. The first line in the chourus is "If I be drounk", not what ever I managed to type previously. I have also found my notes on the history of Isla Waters. Forgive any typos. These are copied sleeve notes from Silly Wizards's Caledonia's Hardy Sons album., the vinyl version. "This song was composed by Martin and Andy around a fragment sung by Andy's grandfather, who was born in Glen Isla in 1900. It tells of a crofter whose life was made difficult by the fact that his local "ale hoose" was across the river from his croft, but miles from the nearest bridge. Crossing to the inn on stepping stones was easy enough in daylight when sober, but returnig after a night of song and powerful whiskey was an entirely different matter."
Hope this helps. Catfeet.
