Here's Tom Anderson's description of why he wrote Da Slockit Light, taken from his book Ringing Strings:

"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 late 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."

I agree with Malcolm. Why mess with something that expresses such a specific meaning for the this composer.
