To play the shuffle parts place your ring finger on the E string, your 
middle on the A string, and use your Index for the shuffle.  Your little
finger should either be on the e or B string.  Hope that helps.

C Am F C G

C
I was drifting
Am
into dreaming
F
and I saw something
  C           G
I hadn't seen before

C
Two young ladies
Am
I hadn't seen since high school
F
holding a piece of me
C                G
inside a plastic jar

Am              C                G (Shuffle between E and F on the e string)
And there was a hook attached to it
Am            C               G
and they were attached at the hip

C Am F C G

C
I was driving
Am
on vacation
F
And I saw something
  C              G
I hadn't seen in years

C
A man was seizing
Am
on the pavement flailing
F
and I did nothing
C                     G
a white dressed woman carried him off

Am       C      G (Shuffle between E and F on the e string)
I didn't lift a finger
Am       C       G
I didn't stop my car
Am     C       G (shuffle between B and C on the B string)
I just kept on driving
Am       C                G
I didn't help that man at all
                          
And I hope he forgives me 

F Am G

The rest of it is basically the same chords with some lead stuff on the e string.
