I found a lot of recordings by Kerr & Fagan, but not "Hauling On." Here's a very poor recording of a performance of the song, apparently by Rose Price at Chester Folk Day:

I can't understand enough of it to even start a transcription.

Do you have any of the lyrics?

It was on a 2010 studio album, Twice Reflected Sun, by Nancy Kerr and James Fagan.
