I have the written words somewhere of a song about John Wilkinson,
or his ilk. Entitled Humphrey Hardfeatures description of cast-iron inventions. It was taken off an LP possibly ARCO (Z) DA86 and the source is listed as , Contributed by the Birminghan Folk Centre.

Most of the words and tune are in my head but im having trouble with my retreival programme today.I may have better luck finding a hard copy.
