I suggest you read Jez Butterworth's Jerusalem (Nick Hern Books, London, 2009). He lived in Pewsey and wrote a brilliant play based on the people and places around him. He really knew Wiltshire, its people, its history, and loved its traditions.
Apologies for takeover!
Two things everyone should know about Pewsey - it was (is?) the largest village in England, it also has the oldest roundabout in the country.
