Lead singer may perform series of concerts on radio (6)
I believe the answer is:
cantor
'lead singer' is the definition.
(I've seen this before)
'may perform series of concerts on radio' is the wordplay.
I cannot really understand how this works, but
'may' could be 'can' (synonyms) and 'can' is found within the answer.
'of' could be 'o' and 'o' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cantor that I've seen before include "Synagogue official who sings and leads prayer - contra (anag)" , "leading chorister" , "Singer in a Jewish synagogue" , "Carton (anag.)" , "Synagogue prayer leader" .)
