Dylan's forte is 'reporting back' to THE Hook, the title.
I noticed recently that "Tangled Up In Blue" isn't a very clear title, a clearly meaningful summation of what the Song's storyline is about. Yet, by simply 'reporting back' to it at the end of long, poetic Verses, it works to tie the whole together, perhaps Melodically overcoming its Lyrical obscurity.
It is a 'Refrain-Type' Chorus, a single Line of Lyric/Melody, as opposed to a Stanza-Type comprised of several Lines with THE Hook among them.
"Cajun Lady" 'reports back' to THE Hook in a similar manner, a Stanza-Type Chorus, ending with THE Hook, the strategic last Line position, left ringing in the ear as the Chorus ends. It's all about her, so she gets the emphasis.

There will always be another song to be written. Someone will write it. Why not you? www.garyeandrews.com
