Dear Jake,
Orwell was quite good at this - although you may think him out of date.
You have obviously read this at some point:

Here you have Orwell writing on the nation of shop keepers and stamp collectors - you can draw a parallel with Winston in 1984 when he hears the "Bells of St.Clements" nursery rhyme. At first you could think that this is somehow a sign that a culture cannot be eradicated - but then - why did Orwell reduce the sum of pre-Big Brother "art and culture" to a clipped piece of a Nursery rhyme?
Here you can see some slightly earlier English Culture:
http://dl.lib.brown.edu/mjp/journals.html BLAST in particular (Although it was written in part by Americans and an Anglo-Canadian). BLAST, in part, deals with a lack of national identity for the English/British and they associate England with being seafarers, nomads, adventurers.
As for Modern British culture we have "The New Plain Style" in Poetry which can be rather good, we have young artists producing reasonable work. And "The Pub" still exists in one form or another - so it can't be all bad!
All the best,
Spare Ed
