Yes, it is funny how the brain makes odd connections. I viewed the "youtube" link and enjoyed it. I love those old film clips.it is what came into my head when I read this, forgive me.
A smell can bring back a memory and maybe the pain you found in Henry Lawson's poem connected with the pain you felt at another time, that time back there in the 80's.
It fits the theme of "lost love" and mabe Poe was right.
So who was it that you felt so much for who didn't remember you?

Lizzy, you seem to understand the poet as well as the poem.
Joney wrote,
Yes Joney, he was talking about himself. And if we are lucky, we know or have met someone like Henry in our life. Bleak and beautiful.(I have a friend like that)I didn't realise that he was talking about himself, I thought he was talking about others.
Henry was brave and empathetic, without ego in his writing; he saw and recorded the pain and the beauty in others and rarely "cared" for himself.
Why does a man like that destroy himself?
Maybe it was that girl.
I think Maud may have understood Henry's pain.

Where the wild wide oceans flow;
Do you know how the heart of a man can bleed
Do you think that I do not know?
