It seems Series 4 onwards is the Water names theme while Series 1-3 was the Bird names (Sparrow, Nightingale, Magpie, Finch)”
HAHAHAH! Love it! I'd forgotten/not noticed the 'bird' names either, thank you
I was watching an old episode of 'The Grand' the other day ( and yes I am a bit emabarrased..) which RTD scripted and I loved yet more use of the 'Harkness' surname in it.
Well, let's hope we get a wave of these new water names in the coming series ( yes that WAS a rubbish pun)
