When Bob Copper's grandfather ...

Peacehaven didn't exist in "Brasser" Copper's time. Since he was bailiff of a 3000 acre farm in charge of 65 men, he probably didn't have time for 7 hours practice a day. Whether he had to sing for his beer in the Black Horse in Rottingdean is debatable since his brother Thomas was the landlord.

Was he a folk singer? I think so. Whether or not he was a professional is utterly irrelevant.
