Guitar chords for the chorusand verses are the same and repeat until the end of the song 
in this progression:
C
C
F C
Dm F
C
C
F C
F G C
the song begins with the chorus. For some reason the formatting for this tab is changing 
as I post it. Chord changes should be on the following words; men, ninety. Never, girl. 
But. Roam, over. together, face, world.  Any corrections are welcome!
C
Oh, there're sober men in plenty,ÿ
C
And drunkards barely twenty,ÿ
                 F                C
There are men of over ninetyÿ
                 Dm                         F
That have never yet kissed a girl.ÿ
C
But give me a ramblin' rover,ÿ
C
And fair Orkney down to Dover.ÿ
             F                          C
We will roam the country overÿ
         F                   G.          C
And together we'll face the world.ÿ

There's many that feign enjoymentÿ
From merciless employment,ÿ
Their ambition was this deploymentÿ
From the minute they left the school.ÿ
And they save and scrape and ponderÿ
While the rest go out and squander,ÿ
See the world and rove and wanderÿ
And are happier as a rule.ÿ

I've roamed through all the nationsÿ
Ta'en delight in all creation,ÿ
And I've tried a wee sensationÿ
Where the company, did prove kind.ÿ
And when partin' was no pleasure,ÿ
I've drunk another measureÿ
To the good friends that were treasureÿ
For they always are in our minds.ÿ

If you're bent wi' arth-i-ritis,ÿ
Your bowels have got colitis,ÿ
You've gallopin' with bollockitisÿ
And you're thinkin' it's time you died,ÿ
If you been a man of action,ÿ
Though you're lying there in traction,ÿ
You will get some satisfactionÿ
Thinkin', "Jesus, at least I tried."ÿ
