This reminds me a lot of what I've noticed through the works of songwriter Dennis Linde, best known for writing "Burning Love."
Throughout the 1980s, Linde wrote a lot of songs about being in love with someone to the point of obsession. Stuff like "What'll You Do About Me":
And what in the world are you planning to do
When a man comes over just to visit with you
And I'm on the porch with a two by two
Baby, what'll you do about me?
Or "I'm Gonna Get You":
I'm gonna get you
You're gonna love me
No doubt about it
I'm gonna get you
Then in the early 1990s, he wrote a song called "Queen of My Double Wide Trailer," about a man named Earl who steals the narrator's girl and then he (the narrator) takes her back. Supposedly, this one was based on a real story.
But Dennis must've come unraveled at some point. Not long after that, you'll start finding that the happier songs from him are replced with sadder titles, like "Night Is Fallin' in My Heart," "Cast Iron Heart," etc. After that, he pretty much backed away from songwriting, until 2000 when the Dixie Chicks put out "Goodbye Earl." And yes, it's the same Earl from "Double Wide."
There was, once again, almost nothing from him until 2005: "Talkin' Song Repair Blues" used car repair as a sarcastic metaphor for songwriting. The song has a rather cynical, critical tone (directed at songwriters) that seems not all that far removed from the "rebelling against the man" theme presented in a 1996 cut titled "Down in a Ditch." Even "It Sure Is Monday" from three years previous shows a general disdain for being a working man.
Not unlike Berke, Dennis Linde was an incredibly reclusive man who rarely let on about his public life.
