This is a great song. I heard my friend Kevin Mitchell sing it not so long ago. I have no doubt that in this form it could well be a translation from the Irish language. Nevertheless, it bears a striking resemblance to a seventeenth century English song called 'Good Ale for my Money'. Here is the first verse and chorus:

BE merry my friends, and list a while

    unto a merry jest,

It may from you produce a smile,

    when you heare it exprest,

Of a young man lately married,

    which was a boone good fellow,

This song ins head he alwaies carried,

    when drinke had made him mellow.

CHORUS:

I cannot go home, nor I will not go home,

    its long of the oyle of Barly:

Ile tarry all night for my delight,

    and go home in the morning early.

This is from the Roxburghe Ballads, 1.138-139 (on line at http://ebba.english.ucsb.edu/ballad/30085/xml )

The themes of the songs are the same and the structure of the chorus bears marked if inconclusive similarity. As we all know, songs get about and change in the getting about.

We included a shortened version of the seventeenth century song on my 1970s compilation 'The Tale of Ale' excellently performed by the Dransfields.
