Demeanour by editor revealing what music director did? (9)
I believe the answer is:
conducted
'did?' is the definition.
(conducting is a kind of doing)
'demeanour by editor revealing what music director' is the wordplay.
I cannot quite understand how this works, but
'demeanour' could be 'conduct' (synonyms) and 'conduct' is located in the answer.
'editor' could be 'ed' (abbreviation) and 'ed' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for conducted that I've seen before include "Led" , "Directed the course of" , "Directed, orchestra say" .)
