I learned this 'version' from the singing of a dear friend, at the time (best part of 50 years ago !) :

"Fare thee well, my own true love.
Fare thee well for a while -
For my ship lies waiting the next flowing tide,
And I am bound away for the sea, Mary Ann (bis).

The crow that is so black, my love
Will change her colour white :
If ever I prove false to thee,
The day will turn to night, my dear Mary Ann (bis)

Oh, but I had a flask of gin -
Sugar here for two
And a great big bowl for to mix them in -
I'd mix a drink for you, my dear Mary Ann (bis).

Repeat 1st verse.

Hope this helps.
