I found these lyrics for "Lowlands," Joan Baez. Not in chanty form.
Not the song sought.

Lyr. Add: Lowlands
Trad., Joan Baez

We sailed out of Dunmore, Michelmass gone by
Cowhides and wool and live cargo
Twenty young Wild Geese ready fledged to fly
Sailing for the lowlands low.

Cho-
The lowlands low, the lowlands low
Sailing for the lowlands low

Sean Rouse the skipper, from the Church of Crook
Piery keeps log for his father
Crew all from Bannow, Fethard and the Hook
Sailing for the lowlands low.

Ready with priming, we'd our galliot gun
Muskets and pikes in good order
We should be riddled, captives would be none [?]
Death or else the lowlands low

The lowlands low, the lowlands low
Death or else the lowlands low

A pirate approached us, many leagues frtom shore
We fought and sunk him in good order
He'll go a-roving, plundering no more
Sailing for the lowlands low.

We smuggled out the Wild Geese, weapons safe ashore
Then we unloaded our cargo
A fair wind blowing, we're headed for Dunmore
Sailing from the lowlands low.

The lowlands low, the lowlands low
Sailing from the lowlands low
Sailing from the lowlands low.
