What is Procol Harum's "Homburg" about?

I could have sworn I posted this last night- If I did and it sank, please delete this- I could not find it in a general search.

If not, does anyone have any ideas on the meaning of the lyrics? Is it a metaphor for something? A simple tale? Drugged out nonsense?

Just so people know what you’re talking about, here are “Homburg’s” lyrics.

You posted it in General Questions. Any my answer is the same as before: It’s about the same thing as “A White Shade of Pale.”
