There is a whole discussion in the above link, about the meaning of this song.  

----------------------------------------------

Well if you've got a wingo take me up to ringo
Where the waxies sing-o all the day
If you've had your fill of porter and you can't go any further
Then give your man the order back to the Quay.

Chorus:

And take her up to Monto, Monto, Monto,
Take her up to Monto, langeroo to you.

You've heard of butcher Foster, the dirty old imposter
He took a mot and lost her up the Furry Glen
He first put on his bowler, then he buttoned up his trousers
And he whistled for a growler and he said, "My men,

(a.s.a.  The Dirty Duke of Gloucester, the dirty old imposter)

Chorus: Take me up to Monto, etc.

The fairy told him, `Skin the Goat,' O'Donnell put him on the boat
He wished he'd never been afloat, the dirty skite
It wasn't very sensible to tell on the Invincibles
They took aboard the principals, day and night.

Chorus: Be goin' up to Monto, etc.

You've seen the Dublin Fusiliers, the dirty old bamboozaliers
They went and got the childer, one, two, three
Marchin' from the Linen Hall, there's one for every cannonball
And Vicky's goin' to send youse all o'er the sea.

Chorus: But first go up to Monto, etc.

When the Czar of Rooshia, and the King of Prooshia
Landed in the Phoenix in a big balloon
They asked the Garda Band to play, `The Wearin' O' the Green'
But the buggers in the depot didn't know the tune.

Chorus: So they both went up to Monto, etc.

The Queen she came to call on us, she wanted to see all of us
I'm glad she didn't fall on us, she's eighteen stone
`Mr. Neill, Lord Mayor,' says she, `Is this all you've got to show to me?'
`Why no, ma'am, there's some more to see - pog mo thoin

Chorus:

And he took her up to Monto, Monto, Monto,
Took her up to Monto, langeroo - Liathroidi to you.


* Pog mo thoin = kiss my ass
