The Fiery Furnaces "My Egypian Grammar"

The Fiery Furnaces have a song My Egyptian Grammar on  their album Widow City:

You'll find the lyrics over here.

I never thought it could have happened to me.
But on the morning of my eldest daughter's
Second wedding, I blacked out.
They said it was just stress, but I didn't think so: 

I couldn't remember the 15 minutes before.
A white-haired half Samoan girl from Darwin
Gave me a ride, it seems; she let me the car in.
But what it was she said, I couldn't say. 

Now, that clearly didn't happen. I consulted my Egyptian Grammar.
On p. 333 was the hieroglyph for motorcycle helmet. 

I combined this with a leather-back's shell as I felt I was instructed.
I Xeroxed it and posted it down by the bike lock-ups at the Oriental Institute.
Maybe a nether-world entity would see it and pass it on to those responsible.
That kind of thing must happen sometimes. 

Now that clearly didn't happen. I consulted by Egyptian Grammar.
On p. 428 was the hieroglyph for French Canal boat. 

I met on the Midway someone channeling up a whatever it wasn't:
There are 17 sections of cymbals in the orchestra of the oversold, it said.
Your youth is lost and doesn't it now seem
You can't make smoke--only steam? 

Now that clearly didn't happen. I consulted my Egyptian Grammar.
On p. 566 was the hieroglyph for a blue jay.

 There must be a back story.  Who can help?
