Portland, Oregon Lyrics

Trying to work out the chords for the entire Van Lear Rose album!!
The riff played by Jack White can be played by power chords at
Frets: 3/6/8 of the Low E string.
The bracketed chords in the middle of the tab is an occurence of this riff.
Well Portland Oregon and sloe gin fizz
If that ain't love then tell me what is
Uh huh, Uh huh
Well I lost my heart it didn't take no time
But that ain't all. I lost my mind in Oregon
In a booth in the corner with the lights down low
I was movin' in fast she was takin' it slow
Uh huh, Uh huh
Well I looked at him and caught him lookin' at me
I knew right then we were playin' free in Oregon
Next day we knew last night got drunk
But we loved enough for the both of us
Uh huh, Uh huh
In the morning when the night had sobered up
It was much too late for the both of us in Oregon
Well sloe gin fizz works might fast
When you drink it by the pitcher and not by the glass
Uh huh, Uh huh
Hey bartender before you close
Pour us one more drink and a pitcher to go
And a pitcher to go
