This song is usually called 'The Banks of Sweet Primroses'. I have a Catnach broadside with it on, the first one I ever bought.

In an earlier version he is a farmer. Banker is a 19th century adaptation and I favour the navvy theory. The 'going on deck' is a corruption.

On 18th century garlands the title is:-
Dialogue Between a Brisk Young Farmer and a Handsome Young Woman.

As I walk'd forth one morning fair
To view the Fields and take the air
I saw a young Farmer all alone
-- to his Sweetheart was making Moan.

He said, my Dear beauty bright
On you I've fix'd my whole Delight
What you say farmer it may be true
But my Answer is I'll have none of you.

My dearest Love I will you deck
With a Chain of Gold about your Neck
But she took huff and away she flew
And her Answer was I'll have none of you.

Now this young Farmer no more could say
So took his leave to march away,
O stay young Farmer I will love
But his answer was I'll have none of you.

He said my Dear I'll tell you plain
My Suit and Proffer you do disdain.
When your love I crav'd you did me deny,
Do you think I'll marry you; No not I.

Now this Maid has her senses lost
For she has oftentimes in love been cross'd
And now she lives in Torment and Woe,
And rues the Time she e'er did so.
