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

     D                 Am                G
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

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

Em       A         G
I'm out wandering around
Em          A              G
you're but one thing I've found
Em       A                 G
I don't mean to bring you down
Em       A         G
I'm out wandering around

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

Em       A        G
I can't hold you near
Em        A       G
you just are not here
Em         A              G
though it wasn't hard or far
Em           A        G
I walked you to your car

(Bm  A   G) repeated singing "Ooooohhh"......
