Party over, that fellow and the writer will make for opera (2,6)
I believe the answer is:
la boheme
'for opera' is the definition.
(I've seen this before)
'party over that fellow and the writer will' is the wordplay.
I cannot really see how this works, but
'party' could be 'lab' (abbreviation for Labour) and 'lab' is found in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is found in the answer.
'fellow' could be 'he' (I've seen this in other clues) and 'he' is located in the answer.
'writer' could be 'me' (the person who is writing these clues) and 'me' is found in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'make' is the link.
Can you help me to learn more?
(Other definitions for la boheme that I've seen before include "18 [OPERA]" , "musical work" , "Opera by Puccini" .)
