The original song is played on an ukulele and not on a guitar.
I noticed that there is not the correct ukulele version available here and I love 
to sing and play it. 
So I copied the lyrics and the progression from Ukulelehunt.com and made this tab out of it!

It's just one progression throughout the whole song: 
C - F - G - F

The G is slightly different:
--2--
--3--
--2--
--4--

Strumming pattern:

--up-down-up--chuck  
(chuck: just jam your hand on all strings to mute them to make a little bassy sound)



C F G F x4

            C          F                 G             F
Oh well in five years time we could be walking round a zoo
          C          F         G      F
With the sun shining down over me and you
                 C            F            G          F
And thereŽll be love in the bodies of the elephants too
                 C               F            G           F
And IŽll put my hands over your eyes, but youŽll peep through


                 C       F   G             F
And thereŽll be sun sun sun all over our bodies
     C        F       G        F
And sun sun sun all down our necks
     C        F       G        F
And sun sun sun all over our faces
     C       F       G        F
And sun sun sun so what the heck


               C         F         G            F
Cos IŽll be laughing at all your silly little jokes
                 C      F            G        F
And weŽll be laughing about how we used to smoke
             C               F           G            F
All those stupid little cigarettes and drink stupid wine
     C             F        G           F
Cos itŽs what we needed to have a good time


             C       F       G          F
And it was fun fun fun when we were drinking
        C       F       G         F
It was fun fun fun when we were drunk
            C       F       G          F
And it was fun fun fun when we were laughing
        C       F     G       F
It was fun fun fun oh it was fun
C F G F x2


           C               F                          G         F
Oh well I look at you and say itŽs the happiest that IŽve ever been
             C             F            G         F
And IŽll say I no longer feel I have to be James Dean
                 C        F            G           F
And sheŽll say "Yeah well I feel all pretty happy too
          C              F                   G               F
And IŽm always pretty happy when IŽm just kicking back with you"


              C         F         G           F
And itŽll be love love love all through our bodies
     C          F         G          F
And love love love all through our minds
           C         F        G        F
And it be love love love all over her face
     C         F        G     F
And love love love all over mine


           C                 F        G           F
Although maybe all these moments are just in my head
           C             F           G        F
IŽll be thinking 'bout them as IŽm laying in bed
             C           F                G          F
And all that I believe they might never really come true
           C         F               G             F
But in my mind IŽm havin' a pretty good time with you

     
 C          F                G   F
Five years time I might not know you
 C           F                G        F
Five years time we might not speak at all
    C           F                G    F
In five years time we might not get along
    C           F                   G        F 
In five years time you might just prove me wrong
