Daniel Johnston - Like A Monkey In A Zoo chords

Daniel Johnston - Like a Monkey in a Zoo
i'm having trouble finding the Daniel Johnston version for reference so im going 
by Kathy McCarty's cover, which i think is in the same key anyway but im not certain.

the main piano tune goes a bit like this (give it a swing):

     G       D         C
E  :-----3---2-0-2-3-|-----------------|
B  :-----------------|-------1---------|
G  :---0-------------|-----0---0-------|
D  :-------0-0-------|---2-------2---2-|
A  :-----------------|-3-----------3---|
E  :-3---------------|-----------------|

the tune's just in the top strings, you can improvise the other part.

                    G, D, C
I'm chained to the wall.
(C)                G, D, C
I have nothin' at all.
(C)     G                  D                  C
And my eyes look into the sunset thinkin' of better things to do,
(C)      G    D     C
Like a monkey in a zoo.

                 G, D, C
The days go so slow.
(C)               G, D, C
I don't have no friends.
(C)     G           D                      C
Except all these people who want me to do tricks for them,
(C)      G    D    C
Like a monkey in a zoo.

G, G7
                        C, G/B, Am
And it could happen to you.
(Am)            G
You could be in my place.
G7                         C, G/B, Am
No it wasn't always like this,
(Am)                D7
But I never saw it comin'.


          G, D, C
I'm so alone,
(C)             G,  D, C
But this is my home.
(C)      G         D                         C
And the bars that surround me keep me from knowin' any better,
(C)      G    D    C
Like a monkey in a zoo.

            G,    D, C
Throw me a peanut.
(C)             G,  D, C
Laugh and make jokes.
(C)       G             D               C
But I've had enough of peanuts and I'm ready to choke,
(C)      G    D    C
Like a monkey in a zoo.

G, G7

                       C, G/B, Am
You come to look at me.
(Am)          G
You seem so amused.
G7                       C, G/B, Am
But things would look different
(Am)           D7
If you were in my shoes.


                G,  D, C
I know its my fault,
(C)         G,  D, C
But I want out.
(C)         G       D               C
And when I cry out nobody seems to understand,
(C)      G    D    C
Like a monkey in a zoo.

             G,  D, C
You say I'm cute.
(C)                           G,  D, C
You don't know how much that hurts.
(C)         G           D       C
You don't know how it feels to live in your own dirt,
(C)      G    D    C
Like a monkey in a zoo.

G, G7

                        C, G/B, Am
And it could happen to you.
(Am)            G
You could be in my place.
G7                   C, G/B, Am
Don't let yourself slip.
(Am)                    D7
Don't keep egg on your face.

              G,  D, C
I used to be happy.
(C)                     G,  D, C
I can't remember those days.
(C)    G       D                C
But I sold my freedom for free room and board,
(C)      G    D    C    G
Like a monkey in a zoo.
