About time to take in nude show (7)
I believe the answer is:
cabaret
'show' is the definition.
(I've seen this before)
'about time to take in nude' is the wordplay.
'about' becomes 'ca' (abbreviation for 'circa'**).
'time' becomes 't'.
'to take in' means one lot of letters goes inside another.
'nude' becomes 'bare' (I've seen this before).
'ca'+'t'='cat'
'cat' placed around 'bare' is 'CABARET'.
(Other definitions for cabaret that I've seen before include "Entertainment at restaurant" , "Floor-show as in nightclub" , "Musical - nightclub entertainment" , "Bob Fosse musical with Liza Minnelli" , "Evening entertainment as in nightclub" .)
