Hello,

I've got a (pretty worn out)cassette from the 70s on which there is
The Song of the Derbyshire Man; Ring, dong, dilly dong; Four pence a day; It's true, me lads; It's dark as a dungeon; In the dear old county of Cornwall; Home-made brew, and John Barleycorn.

And it says there very clearly "Song of the Derbyshire man was written by Ken Campbell.

I like this song, too.

Best wishes :-)
Walter
