An idea that occurred to me that could chime in with the idea of having the CD enclosed between two love songs 20 years and more to the same love. Maybe you could be having the songs in between in some way telling the story of the years in between. I don't mean so much the personal story, the things happening in the world that prompted songs. And the linking idea of loyalty and solidarity, which is, from what I've seen of your songs, Larry, a continuing theme.
As you say the new song is short for you - I have a feeling it might grow an extra verse - there's a lot compressed into that last verse. From the thread about commitment here on the Mudcat, we know what you are talking about - but I'm not sure that it'd come over to a listener.
And maybe one quibble - I'm not sure about that last line, especially the "ounce"; and does "commitment" as a word have the strength of "anchor" and "loyalty" and "true"?
I think this is one of the occasions where, if it was my song, I might try writing out the thought I'm trying to get across in prose, and then see about turning it into verse.
