Came across that piece on sugarman.org. An awesome site when you want to know 
about Sixto Rodriguez. However, listening to the song and watching some videos I 
reckon the version with the 7 chords much more fits what he plays. Check it out

    
Em             A          Em7       A7
Born in the troubled city
Em                A     Em7   A7
In Rock and Roll, USA
Em                           A        Em7   A7
In the shadow of the tallest building
Em                  A         Em7     A7
I vowed I would break away
Em                     A       Em7    A7
Listened to the Sunday actors
    Em                     A      Em7
But all they would ever say
                             Em
That you can't get away from it
A                          Em      A
No you can't get away
                           Em                     
No you can't get away from it
A                        Em
No you can't get away
Em             A          Em7       A7
Schooled on the city sidewalks
Em             A          Em7       A7
Coldness at every turn
Em             A          Em7       A7
Knew I had to find the exits
Em             A          Em7       A7
I never, ever would return
Em             A          Em7       A7
Scoffed at the prophet's omens
Em             A          Em7       A7
That said I would live to learn
Em             A          Em7     
That you can't get away from it
Em.         A
no you can't get away
Em.       A.   
no you can't get away from it
Em.      A
no you can't get away

Em             A          Em7       A7
Going unaided (up 80?) toward the west coast
Em             A          Em7       A7
Stopped in the sleepy town
Em             A          Em7       A7
Left my change and walked out
Em             A          Em7       A7
I didn't even turn around
Em             A          Em7       A7
What they were getting next to
Em             A          Em7       A7
Was that old familiar sound
Em             A          Em7       A7
That you can't get away from it
Em.        A
no you can't get away
Em.      A
no you can't get away from it
Em.     A
no you can't get away

Em             A          Em7       A7
In a hotel room in Amsterdam
Em             A          Em7       A7
On a wild and windy August night
Em             A          Em7       A7
As a cloud passed over a cold moon
Em             A          Em7       A7
My heart was seized with terror and fright
Em             A          Em7       A7
Seeping up through the floorboards
Em             A          Em7       A7
Coming in through the walls
Em             A          Em7       A7
Coming in through the doorway
Em             A          Em7       A7
Ringing up and down the halls
Em             A          Em7      
That you can't get away from it
Em
no you can't get away
A       Em            A7
no you can't get away from it
Em      A      Em7    A7
no you can't get away
Em         A
no you can't get away
Em       A
no you can't get away
Em      A
no you can't get away...
