Have caught bits of both (?) episodes so far. First one was middle-class family somewhere, then last night I think was Manchester +Chillingham Castle, Northumberland (I cycled past there last weekend

).
The Manchester working-class family gave them (cellophane-wrappd) Eccles cakes as a parting gift, which made me smile.

Follow the link through to John Frum, too. The cargo-cult stuff is fascinating (and an interesting sideline to the religion stuff over on Soapbox). I'm sure it was through a discussion on C+ that I first looked up cargo cults.
