I have two favorites, that were collaborations between the Dubliners and the Pogues.
The Irish Rover
The Mountain Dew.
The Irish Rover's awesome.
For a sailor, it's always a bother in life
He's so lonesome, by night and by day
That he longs for the shore, and a charming young whore
who'll melt all his troubles away
Oh, the noise, and the rout, swilling poteen and stout
For him, soon the torment's over
Of the love of a maid, he was never afraid
An old salt from the Irish Rover
