Perhaps West comes online — no, no good for conductors (7)
I believe the answer is:
maestri
'conductors' is the definition.
(I've seen this before)
'perhaps west comes online no no good' is the wordplay.
I cannot really understand how this works, but
'west' could be 'mae' (actress Mae West) and 'mae' is located in the answer.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for maestri that I've seen before include "Famous conductors" , "Top conductors" , "Distinguished conductors" , "Distinguished musicians" , "Experts" .)
