I learnt it at my primary school in Trinidad and have been searching for it online for a long time. I remember all the words, but I wouldn't have guessed back then that it was "Oe" and not "o" or "oh". Here's the version I learnt.. :

Proudly sweeps the rain cloud o'er the plain
Borne swiftly by the western gale
And the song of lovers' parting grief
Sadly echoes amidst the flowering vale
   
         Aloha O! Aloha O!
         The winds will carry back our sad refrain
         One fond embrace before we say goodbye
         Until we meet again
         Farewell to thee! Farewell to thee!
         The winds will carry back our sad refrain
         Until we meet again!

I have fondly watched thy lovely face
Fair rose of Maunawilli's bower
Where the birds sip honey all the day
Fairer far than the dewy opening flower

       Aloha O! Aloha O!
       The winds will carry back our sad refrain
       One fond embrace before we say goodbye
       Until we meet again!
       Farewell to thee! Farewell to thee!
       The winds will carry back our sad refrain
       One fond embrace before we say goodbye
       Until we meet again!
