This is Vic Smith speaking cookie-less and briefly from Corsica -
The excellent Copper Family are probably unique in Britain.
Not quite, Steve. I know of three other examples of their glee harmony folk singing in Sussex. Isabel Sutherland told me of some that she had heard in the Rotherfield area. They were a family of pig farmers. The Lewes singer George Townsend reported singing in this sort of harmony with his father and others when his father kept the 'Jolly Sportsman' four miles outside Lewes at Eaat Chiltington in the late c19. Luther Hills collected by Bob Copper in the 1950s was blacksmith in East Dean and said that he sang in harmony with his father and others and fially there is the family (Millin or something similar?) that George Fraanpton recorded in Kent
