Managed, after concession on orchestra's lead singer (7)
I believe the answer is:
soprano
'lead singer' is the definition.
(thesaurus)
'managed after concession on' is the wordplay.
'managed' becomes 'ran' (I've seen this before).
'after' means one lot of letters go next to another.
'concession' becomes 'sop' (sop is a kind of concession).
'on' becomes 'o' (I've seen this in other clues**).
'ran' put after 'sop' is 'sopran'.
'sopran'+'o'='SOPRANO'
'orchestra's' is the link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for soprano that I've seen before include "Singer who aims high" , "Sutherland?" , "High singing voice" , "chorus girl, perhaps" , "Singer of high notes" .)
