Odds on getting good service (8)

Ross

I believe the answer is:

evensong

Here is my best explanation:

'service' is the definition.
(thesaurus)

'odds on getting good' is the wordplay.
'odds' becomes 'evens' (I've seen this before).
'getting' means one lot of letters go next to another.
'good' becomes 'g' (abbreviation).
'evens'+'on'+'g'='EVENSONG'
