Interestingly there appear to be 2 version of EPW125, Dublin Saunter/Kilcock (white label issued in the 80s) and Dublin Saunter/The Man My Mother Married! (yellow label issued in 60s)

You can try contacting the two members of 45Cat Forum who own it (Fokeman and Mister Haney; if Fokeman's name is a clue he might be willing to help) and see if they'd send you an mp3 of the tune. (Or maybe collectors don't play the records!)
