Jazz fan bored by nude club (7)
I believe the answer is:
cabaret
'club' is the definition.
(I've seen this before)
'jazz fan bored by nude' is the wordplay.
'jazz fan' becomes 'cat' (slang term for a jazz fan).
'bored by' is an insertion indicator (to bore something can mean to drill into it).
'nude' becomes 'bare' (synonyms).
'cat' enclosing 'bare' is 'CABARET'.
(Other definitions for cabaret that I've seen before include "Bob Fosse musical with Liza Minnelli" , "Floor-show as in nightclub" , "Entertainment at night club" , "Nightclub entertainment, floor show" , "Floor show and name of great musical" .)
