For my notes, I copied one of the Bodleian broadsides (Printed for Wm. Armstrong, Liverpool). I was wondering if there was an Irish version but there doesn't seem to be.
It has the "Polly" verse of the Sharp version, above, and would be verse 3 of the one posted by Liam's Brother. Very close to the one given by Graham Pirt.

Give my love to Polly, she's the girl I adore,
Likewise to my Susan, altho' she is poor.
Give my love to Betsy she's my joy and delight,
I'll clasp her in my arms on a cold frosty night.

The last verse is similar to the one in Liam's Brother post but nods to the king.

They are both bound to America and the ship has set sail,
Kind heaven protect them with a prosperous gale,
And when they are landed they'll dance and they'll sing,
In a plentiful country and God save the king.
