what the Coppers did, which was a family raher than a general folk style
I can't think of many other singers who sang as they did

Recent research, some of it uncovered by those working under the banner of Sussex Traditions (inclusing self) are uncovering examples - recordings and written references - of other families who sang in the "alternating glee harmony" of the Copper Family - the Hills of East Dean. the Townsends of East Chiltington, The Millens in faraway Kent. There are also accounts of a Victorian carol group in Falmer and a choir that sang folk songs in Ditchling - both with similar repertoires to the Coppers. Still much to be investigated but progress is slowed by the time that one of the team wastes on Mudcat.
