Rowdy gathering - accept danger’s involved (4,6)
I believe the answer is:
bear garden
'rowdy gathering' is the definition.
The definition suggests a singular noun which matches the answer.
'accept danger's involved' is the wordplay.
'accept' becomes 'bear' (synonyms).
'involved' indicates an anagram (involved can mean confusing or complex).
'danger' is an anagram of 'garden'.
'bear'+'garden'='BEAR GARDEN'
Can you help me to learn more?
(Other definitions for bear garden that I've seen before include "Scene of disturbance" , "Scene of uproar and confusion" .)
