Service odds good after performing? (8)
I believe the answer is:
evensong
'service' is the definition.
(thesaurus)
'odds good after performing?' is the wordplay.
'odds' becomes 'evens' (I've seen this before).
'good' becomes 'g' (abbreviation).
'after' means one lot of letters go next to another.
'performing?' becomes 'on' (I've seen this in other clues).
'g' after 'on' is 'ong'.
'evens'+'ong'='EVENSONG'
(Other definitions for evensong that I've seen before include "6 [SERVICE] ?" , "Church service late in the day" , "... Prayers" , "Service of evening prayer in Church of England" , "Religious service" .)
