The "D Am G"-parts are probably played like this:
(NB! This representation does not reflect the rhythm of the strokes)

     D5                 A5                G5
E--0-----5---0--0--0---0----7---0--0--0--3-
B--3/7---7---7--7--7---0----0---0--0--0--0-
G--3/7---7---7--7--7---5----5---5--5--5--0- ....
D--0------------0------7-----------7-----0-
A----------------------0-----------0-----2-
E----------------------------------------3-
   ^     v   v  ^  v  ^    v   v  ^  v  ^  ....

( ^ = downstroke, v = upstoke, / = slide)

(If you are having problems playing the above chords remember to
 use pinky and ringfinger for B and G strings on D chord when sliding.)

(D Am G) x 2

D5       A5                 G5
Got me watching your eyes watching things go by outside
D5       A5           G5
out the window of a train
D5     A5                G5
easy sipping them just seeing it fly left to right
D5         A5               G5
pour the milk and I'll say when

E5       A5         G5
I'm out wandering around
E5          A5              G5
you're but one thing I've found
E5       A5                 G5
I don't mean to bring you down
E5       A5         G5
I'm out wandering around

D5      A5                 G5
kinda hoped you wouldn't blame me
                  D5    A5               G5
I can't wake up every day and find the same me
D5        A5                   G5
you can scream but I'll just dream how you might disappear
D5      A5                 G5
all I know is it's never clear

E5       A5        G5
I can't hold you near
E5        A5       G5
you just are not here
E5         A5              G5
though it wasn't hard or far
E5           A5        G5
I walked you to your car
