Performance at one time given in clubs, right? (7)
I believe the answer is:
concert
'performance' is the definition.
(I have seen 'Musical performance ' mean 'concert' so perhaps 'performance' could also mean 'concert')
'one time given in clubs right?' is the wordplay.
'one time' becomes 'once' ('once' can be a synonym of 'one time'**).
'given in' is an insertion indicator.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'right?' becomes 'rt'.
'c'+'rt'='crt'
'once' placed within 'crt' is 'CONCERT'.
'at' acts as a link.
(Other definitions for concert that I've seen before include "Joint action" , "Some entertainment" , "Harmony, performance" , "Musical event" , "Harmony of people's opinions, actions or characters" .)
