The Alan Parsons Project's "Snake Eyes"

This morning I listened to the first disc of The Essential Alan Parsons Project.  I listened to "Snake Eyes" (from The Turn of a Friendly Card) twice because I thought I noticed something and then wanted to confirm it while looking at the lyrics.

There's a recurring section, but there are changes in it for every reptition.  The first section (referenced from the lyrics section on the Alan Parsons Project's website) is:

Just one minute more, give me just one minute more
It's gonna be alright, it's gonna be alright
Just one minute more, then I'll walk right through that door
It's gonna be alright, it's gonna be alright, if ya gimme

The second iteration includes more of the "gimme one (minute) more" line:

Just one minute more, gimme just one minute more
It's gonna be alright, it's gonna be alright, but'cha gotta
Gimme one minute more, gimme one more, gimme one minute more
It's gonna be alright, it's gonna be alright

The final section adds "gimme one more" in the backing vocals, and the second half changes the "minute" to "marker" (which I'll admit I didn't notice until looking at the lyrics).  The APP website formats this verse differently (ostensibly to accommodate the backing vocal parts), which I've followed here:

Just one minute more (Gimme one more)
Then I'll walk right through that door (Gimme one more, gimme one more)
It's gonna be alright (Alright)
It's gonna be alright, but'ya gotta 

Gimme one marker more (Gimme one more)
Then I'll
 walk right through that door (Gimme one more, gimme one more)
Gimme one more (Don't let me down)
It's gonna be alright, alright, alright

As that section is repeated, the "gimme one more" occurs more and more frequently, and - along with the switch from "Gimme one minute more" to "Gimme one marker more" - this illustrates something of a gambling addiction.  The singer/speaker can't pull himself away from his insatiable need.
