Western Paris street covered with a bit of Tarmac and gravel (4,4)
I believe the answer is:
true grit
'western' is the definition.
(I've seen this before)
'paris street covered with a bit of tarmac and gravel' is the wordplay.
'paris street' becomes 'rue' ('street' in French).
'covered with' is a charade indicator (letters next to each other) (in a down clue, some letters go on top of others).
'a bit of' suggests taking the first letters.
'and' is a charade indicator (letters next to each other).
'gravel' becomes 'grit' (I've seen this before).
The first letter of 'tarmac' is 't'.
'rue' after 't' is 'true'.
'true'+'grit'='TRUE GRIT'
(Other definitions for true grit that I've seen before include "Film" , "movie" , "vehicle for John Wayne" , "Western" , "Genuine courage (John Wayne's)" .)
