Ok, so on the album I think he uses a kind of open tuning, but when he pays it 
live, he uses standard tuning in the key of C. Here are the chords as far as I can 
make them out.  He is travis picking. Hope this is helpful!

Intro: C
      C      F-G-C                     Em        
So now I am older                  
                       F               Em
than my mother and father
                      Am
when they had their daughter
    G               F          G     G7
now what does that say about me?

Oh how could I dream of such a selfless and true love
could I wash my hands of
just looking out for me?

      F      Em     Am
Oh man what I used to be
Em   G    Em   Am   F     G      G7
Oh  man  oh   my   oh   me
     F      Em      Am
Oh man what I used to be
Em   G    Em  Am   F    G      G7
Oh  man  oh   my   oh   me

In dearth or in excess 
both the slave and the empress
will return to the dirt, I guess, naked as when they came

i wonder if I'll see any faces above me
or just cracks in the ceiling
nobody else to blame?

Oh man what I used to be
Oh man oh my oh me
Oh man that I used to be
Oh man oh my oh me

INTERLUDE (this part I am less sure about)
F Am G
Ohhhhhhh
F Am G F G
Ohhhhhhhh

Gold teeth and gold jewelry
every piece of your dowry
throw them into the tomb with me
bury them with my name

Unless i have someday
Ran my wandering mind away

Oh man what i used to be
Montezuma to Tripoli
Oh man oh my oh me
