Fine time carousing before street party (11)
I believe the answer is:
oktoberfest
'fine time carousing' is the definition.
I can't tell whether this defines the answer.
'before street party' is the wordplay.
I cannot quite see how this works, but
an anagram of 'before' is 'oberfe' which is within the answer.
'street' could be 'st' (abbreviation) and 'st' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for oktoberfest that I've seen is " German beer celebration".)
