Hi Tom!
Given that you had provided me with some analysis of my own rhyme schemes, I thought I would return the favour. You might know that I'm a self-confessed lyrics atheist (or is that agnostic?) so knowing the attention you pay to the words, I thought I had better have a closer look.

First thing that stood out to me was the rhyme scheme of the verses: first two lines rhyme; lines 3 and 5 rhyme; which made me think lines 4 and 6 would rhyme but they don't - so it leaves line 6 hanging in an unrhymed state - it made me wonder if that (the unresolved rhyme) accentuates the question? I think it does. Then lo and behold, in the final verse, the rhyme is resolved (lines 6 & 7 - do/you) like an affirmation of his love for his wife.

I like the line 'And Alaska it might as well be Mars' - similar in terms of solitude and distance (no offense to those in Anchorage and Fairbanks), but also contrasting in terms of landscape - white/grey vs red.
Also the line 'It seems in the scheme of things' - a micro alliteration. The other thing I liked was you used phrases that accentuate the length in time and distance ...

And with every shortened day
...
Comes the cursed, lonely night;
...
​Our lives so far apart,
...
And Alaska it might as well be Mars;
...
But in Alaska the nights are real lonely
And the winter's endlessly long.
...
As empty as our home might be,
We can hold out till the spring;
Then I'll be there to spend the summer's end;


Really enjoyed this deep dive into your lyrics!
Andrew
