Dali perhaps not unknown among county celebs (10)
I believe the answer is:
surrealist
'dali' is the definition.
(I've seen this before)
'county celebs' is the wordplay.
'county' becomes 'surre' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'celebs' becomes 'a list' (I have seen 'Top celebs' mean 'a list' so perhaps 'celebs' could also mean 'a list').
'surre'+'alist'='SURREALIST'
'perhaps not unknown among' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for surrealist that I've seen before include "Dali or Magritte, for example" , "Avant-garde artist" , "Breton, say" , "Magritte perhaps" .)
