Having been brought up in Suffolk, I bought an EP record of Bob Roberts’ singing in the 1960s, which included “the Suffolk version of the Foggy Dew”. It had only 4 x 4-line verses, so maybe cuts a longer story short: I was told when I sang it once , “Oh, that’s the cleaned-up version”!
The tune is totally unlike the other one I knew of: it bears some passing resemblance to “Ye Banks and Braes” but is definitely not the same. I’ll post the words if anyone’s interested. Has to be sung in a broad Suffolk accent.
