From memory, but should serve:

C~~~~~~~~~~~~~~~~~~~~~~F~~~~~~~~~
Farewell to thee, my own true love
C~~~~~~~~~~~~~~~~~~~~F~~~~~~~~~~~~~~~~~~~G
I am sailing in the first hours of the morn
C~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~F
I am bound for the coast of Mexico,
C~~~~~~~~~~~~~~~~~F~~~~~~~~~~~~~~~~G
Or perhaps twill be the bay of Californ'.

C~~~~F~~~~~~~G~~~~~~~F~~~~~~~~~~~G So fare the well, my own true love
C~~~~~~~~~~~~~~~~~~~~F~~~~~~~~~~~~~G
And when I return united we will be;
C~~~~~~~~~~~~~C~~~~~~~~~~~~~~~~~~~~~~~~F~~~~~~~
It's not the leaving of Liverpool that grieves me
C~~~~~~~~~~~~~~~Dm~~~F~~~~~~G~~~~~~~~C
But my darlin' when I think of thee.

You may need to slide these around a little, and the words are not guaranteed pure. I'm not guaranteed pure my own self, either, but these will get you through.
