Yes, Derry City Council exists there :wink: . I should have called it the 'Maiden City'.
The tour guide actually started off with the naming of the City and the arguments it causes. Basically said you can call it what you want & nobody gives a sh_it. During the City of Culture year it was called 'LegenDerry'. It's funny because on the drive over most of the road signs have the London part spray painted over. Mad place.
