Ok, so I was slightly appalled my the version of this song, so I decided to clear this up, here is the 
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?
