Dear sjm: You have led me to the solution of a mystery. Quite a few years ago
I used to prowl through hundreds of acres of forest surrounding a public water supply.
There were empty houses still standing in a few places. One of them had a very
decrepit Chick Sale, with an elaborate enamelled blue and white street sign
"Carnaby Street". I could not imagine what significance it had.
Your post promptem me to search and find origin of that name. Thanks
