I have a the Recording of Stan Hugill at Mystic Seaport and I have an LP of BLOW BOYS BLOW with A.L. Lloyd and Ewan MacColl (SP?). Not exactly pretty voices, great engineering or lots of showy ornamentation. I like it.

Who else out there was/is as "salty" in their performance style? While avoiding really bad voices and truly rotten recordings.
I know I've butchered the spelling of the names but I hope you get the Idea.
