Show bearcat fighting (7)
I believe the answer is:
cabaret
'show' is the definition.
(cabaret is a kind of show)
'bearcat fighting' is the wordplay.
'fighting' indicates an anagram (I've seen this in other clues).
'bearcat' anagrammed gives 'CABARET'.
(Other definitions for cabaret that I've seen before include "Bob Fosse musical with Liza Minnelli" , "Entertainment provided in a nightclub" , "Variety entertainment" , "Floor show and name of great musical" , "Floor show for Arab etc" .)
