Crossword Genius

Service odds good after performing? (8)

Ross

I believe the answer is:

evensong

Here is my best explanation:

'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'
