Uproarious scene? Put up with it, keeping quiet (4,3)
I believe the answer is:
bear pit
'uproarious scene?' is the definition.
(bear pit can mean a chaotic scene)
'put up with it keeping quiet' is the wordplay.
'put up with' becomes 'bear' (synonyms).
'keeping' indicates putting letters inside.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'bear'+'it'='bearit'
'bearit' placed around 'p' is 'BEAR PIT'.
(Other definitions for bear pit that I've seen before include "rowdy scene" , "Place full of aggressive, competitive types" , "Stock Exchange?" , "rowdy place" , "part of the zoo" .)
