Boldness of wine reviewed by band at party (7-2)
I believe the answer is:
derring-do
'boldness' is the definition.
(I've seen this before)
'of wine reviewed by band at party' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
'band' could be 'ring' (a ring is a band of metal) and 'ring' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for derring-do that I've seen before include "Courageous action" , "Brave acts" , "heroic deeds" , "Brave and heroic feat(s)" , "Literary word for heroic courage or action" .)
