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 (320003@1)     D (xx0232@1)       CE (x32010@1) :-----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.
