OK! Here are my updated notes on A Sailor's Garland (1962).

Not unsurprisingly, at this point there is a great influence of Hugill's work on the performers.

Haul Away for Rosie
MacColl.
Seems based in Hugill SfSS, but melody is reinterpreted. Major (Ionian) becomes Mixolydian.

Tom's Gone to Hilo
MacColl.
From Hugill SfSS.

Sally Brown
Lloyd.
From Sharp (1914). However, this was also in Hugill SfSS, and without any other indication that he'd used Sharp's collection, I'd guess he got in from Hugill. (Damn, his added "n***er" lines seems to me uncalled for.)

Hilo Somebody
Lloyd.
A synthesis of Terry and Hugill SfSS.

Little Sally Racket
This time led by MacColl.
Like Lloyd's on earlier album, but sung in ametrical style where the soloist keeps coming in early after the choruses.

Gal with the Blue Dress On
Lloyd.
From Hugill SfSS

Bring 'em Down
Lloyd.
Evidently adapted from Jekyl's collection of Jamaican songs. See here:

Hilo John Brown
MacColl.
After Terry, with additions and mis-readings of score.

General Taylor
Lloyd.
Originally appeared in Sharp, but was reproduced in Hugill SfSS, which is probably where they found ir.

Bold Riley O
Lloyd.
