Service still good around noon (8)
I believe the answer is:
evensong
'service' is the definition.
(type of church service)
'still good around noon' is the wordplay.
'still' becomes 'even so' (both can mean 'nonetheless').
'good' becomes 'g' (abbreviation).
'around' means one lot of letters goes inside another.
'noon' becomes 'n'.
'evenso'+'g'='evensog'
'evensog' placed around 'n' is 'EVENSONG'.
(Other definitions for evensong that I've seen before include "Vespers" , "Church service late in the day" , "... Prayers" , "Late afternoon church service" , "Anglican service" .)
