Quits just after Goran's first service (8)
I believe the answer is:
evensong
'service' is the definition.
(thesaurus)
'quits just after goran's first' is the wordplay.
'quits' becomes 'evens' (I've seen this before).
'just after' becomes 'on'.
'first' says to take the initial letters.
The initial letter of 'goran' is 'g'.
'evens'+'on'+'g'='EVENSONG'
(Other definitions for evensong that I've seen before include "Religious service" , "Service of evening prayer in Church of England" , "Vespers" , "Anglican service" , "6 [SERVICE] ?" .)
