I am going to skip over the second Critics group shanties recording because it looks like more stuff straight out of the books (Colcord and Doerflinger).

The last (?) batch of chanties introduced by Lloyd or MacColl then, is:

7. Sea Shanties (with Roy Harris) (1974)

Lloyd seems to have hit the jackpot in discovering recordings of The Bahamas/Caribbean. I'd kill to know what he thought when he heard "Come Down You Bunch of Roses," which he would surely have when exploring the recordings.
