Steve, thanks for reminding me about "Jolly Sailors Bold"! I actually forgot that I have it. Somewhere.

I've also canvassed ECCO for key phrases like "Spanish ladies," "rant an we'll roar/ rove," and "Ushant to Scilly" without finding another 18th century text.

Nothing in the 17th either (EEBO) but Deloney's 1695 ballad "The Spanish Ladies Love," which bears no relationship beyond the title and a "Captain."

GUEST, it's certainly one my favorites.
