Monty Python - The Lumber Jack Song guitar chord

Ok, so I was slightly appalled my the version of this song, so I decided to clear this up, here is the correct version of "The Lumber Jack Song"

G C

oh, I'm a lumberjack and I'm okay

D D7 G C G

I sleep all night and I work all day

G C

he's a lumberjack and he's okay

D D7 G C G

he sleeps all night and he works all day

G C

I cut down trees, I skip and jump

D D7 G C G

I like to press wildflowers

G C

I put on women's clothing

D D7 G C G

And hang around in bars

That's the whole chord progression of the song! Easy, eh?
