One thing I never understood about Supergran was that it was set in Scotland but made by Tyne-Tees.

It just depends on which company came up with the idea of making the programme and buying the rights. I suppose their patch isn't too far from Scotland

Around the same time Thames were making their two Adrian Mole series in South West London despite it being set in the midlands.

Another that springs to mind is Wycliffe which was an HTV production despite being set in Cornwall
