Fine old stories presented by composer before cabaret (6,7)
I believe the answer is:
folies bergere
'cabaret' is the definition.
(Folies Bergre is a cabaret in Paris)
'fine old stories presented by composer before' is the wordplay.
'fine' becomes 'f' (abbreviation).
'old' becomes 'o' (abbreviation).
'stories' becomes 'lies' (to tell stories can mean to lie).
'presented by' is a charade indicator (letters next to each other).
'composer before' becomes 'bergere' (I am not sure about this - if you are sure you should believe this answer much more).
'f'+'o'+'lies'+'bergere'='FOLIES-BERGERE'
(Other definitions for folies bergere that I've seen before include "Music-hall" , "French entertainment" , "Here see dancing" .)
