There's a song that goes well with this, and helps explain what it's about, and it's by another emigrant to Australia, this time from Ireland, the songwriter Enda Kenny (not to be confused with an Irish politician of the same name that no one would want to be confused with).

Don't Ask Me To Sing The Wild Rover
I don't have to try to be green
I'd rather you drove me right over the edge
Of the high rocky cliffs of Doneen
I've left all that behind me now
I'm not homesick any more
And I don't need you to remind me
Of Paddy's green shamrocks shore.

Do you ever stop to ask yourself
Just why it is you left home
What have you seen of the places you've been to
Since you started out for to roam
Is it Mass every Sunday
The pub every night
And five different bands
That all play the same shite
Like Donegal Danny and Dirty Old Town
And a "fine girl you are" in the old Holy Ground.

How many friends have you made over here
Whose accents are not like your own
How is it every time I get to hear you
You're talkin' of going back home
Well I won't be found
Where your sorrows are drowned
With plastic shamrocks and beer
Cause I've chosen to live in Australia
Not in "Ireland Over Here".
