She said that she would never be mine
Nor that her home would ever be
O where that Ireland water flows
On the banks of the obd.

I plonged my knife into her breast
Until she screamed, in agony.
Crying Willie dear, please don't murder me,
On the Banks, of the Oh Bee Deeeeeh

O Father I have commurthored a crime
And it's a crime I confess to thee,
For I have murdered my own true love,
On the banks of the OBD.

Not all the verses, but the pertinent ones.
