Black Ball Line
Lead by MacColl.
After Colcord.

Blood Red Roses
Lead by Lloyd.
After Doerflinger, but seems to be with multiple changes by the singer.

Blow Boys Blow
Lead by MacColl.
Melody perhaps after Terry. The lyrics here are interesting: "Where fever makes the White man shiver." I don't see this idea anywhere accept in Hugill SfSS (1961). MacColl's recording seems to have been 1960 or earlier. I'd suspect one got it from the other. For reasons I won't elaborate here, I actually think Hugill may have took it from MacColl.

"Sailboat Malarkey" must be the Bahamian song Hugill was talking about.
