Show lion perhaps eating wild bear (7)
I believe the answer is:
cabaret
'show' is the definition.
(cabaret is a kind of show)
'lion perhaps eating wild bear' is the wordplay.
'lion perhaps' becomes 'cat' (lions are big cats).
'eating' is an insertion indicator.
'wild' indicates an anagram.
'bear' with letters rearranged gives 'bare'.
'cat' enclosing 'bare' is 'CABARET'.
(Other definitions for cabaret that I've seen before include "Musical - nightclub entertainment" , "Bear cat (anag.)" , "Nightclub entertainment, floor show" , "Floor-show as in nightclub" , "Nightclub 12ac" .)
