How was this song written? Did he just ignore the question of where he was at any given point and let the exposition go on over four sections, one minute and thirty-nine seconds, as it pleased to suit the poetry?
Because you seem to start with the chorus, but it evolves over four lines as though it were a verse. And then there's another one, with new words. Two choruses to start a song?
That would seem to be the case. The next section ("Got laid off down at the factory" etc.) is a verse proper. Notice how it uses the harmonic vocabulary of the part of the chorus that sounded like a verse!
This section has an extension that turns out to be a bridge. That's clever placement but perhaps cleverer still is the fact that it turns out NOT to be exploratory, quickly returning to the haunting progression you'll hear a couple more times when he repeats the two choruses.
