Here in Northumberland it's pronounced "Berrick" in the south of the
county, becoming "Ber'rick" as you get further north.
We have a Berwick in East Sussex which the railways insist on labeling
Berwick (Sussex) on timetables, as they do with Hampden Park just outside
Bit off topic but it is a Friday one!
