Easy wee song, but class anyways.
Key of G

e------------------------------|
b---0-------0-------0-----0----|
g--0-0-0---0-0-0---0-0-0-0-0-0-|
d------------------------------|
a------------------------------|
E-3---3-3/5---5-5/8---8-8---8--|

At the "I don't, don't, want to go today" part,
it just goes from G (3) to C (8).
Occasionally he rolls up to D(10), but it's easy enough to pick out.
Enjoy!
