So, I know this is five years late, but I was looking for the same lyrics and only arrived at this page. Sorry for being the Thread Necromancer; I hope this will satisfy at least someone's curiosity about the song.

I've extracted this song segment from The Bounty soundtrack Forbidden Love and have listened to it about 297 times continuously, but I cannot discern the lyrics either, beyond this:

If I're a sailor at the sea
I'd take my pretty girl with me
She could cook and care for me
And I'd be the pride of the King's Navy

But alas it is the law
I had to leave her on the shore

(Now, as I hear it):

Venture I will write each day
And in my heart I hope I stay
Tomorrow we are homeward bound
"Sing and reach our English sound" (perhaps something like that)
Sing and dance and when we round
I'll buy my love a wedding gown
