The Bodleian library has 8 versions of this song. I copied thes e lyrics from The Sad and Mournful History of that Amiable and Loving Couple William Rattling and Sweet Poll of Plymouth... (London: W. Bailey, 1784), page 46:

SWEET POLL OF PLYMOUTH.

Sweet Poll of Plymouth was my dear.
When forc’d from her to go,
Adown her cheeks ran many a tear.
My heart was fraught with woe.
Our anchor weigh’d, for sea we stood.
The land we left behind.
Her tears then swell’d the briny flood.
Her sighs increas‘d the wind.

We plough’d the deep, and now between
Us lay the ocean wide.
For five long years I had not seen
My sweet, my bonny bride.
That time I sail’d the world around,
All for my true love's sake,
But press’d, as we were homeward bound,
I thought my heart would break.

The press-gang bold I ask’d in vain
To let me once on shore.
I long'd to see my Poll again,
But saw my Poll no more.
“And have they torn my love away?
And is he gone?” she cried.
My Polly, sweetest flower of May,
She languish’d, droop’d and died.
