Nice one, Glenn - thank you!
By the way, I dislike the title of the tune. 'Slockit' sounds like slog, slug, sluggish... or like an expletive.
Here's what Wikipedia says about it (in it's article on Tom Anderson): "[it] was inspired by the depopulation of the area of Eshaness where he was born. Each time the occupants of another croft moved out, or died, another light was 'slockit', (Shetland for extinguished).
"I was coming out of Eshaness in late January, 1969, the time was after 11 pm and as i looked back at the top of the hill leading out of the district, I saw so few lights compared to what I remembered when I was young. As I watched, the lights started going out one by one. That, coupled with the recent death of my wife, made me think of the old word ‘Slockit’ meaning, a light that has gone out, and I think that was what inspired the tune.” – From a tape recorded interview with Tom Anderson by a student in 1970."
The Husband calls the tune The Light Socket.
