Song making a comeback in chapel or a church (5)
I believe the answer is:
carol
'song' is the definition.
(carol is a kind of song)
'a comeback in chapel or a church' is the wordplay.
'a comeback' shows that the letters should be reversed in order.
'in' indicates the answer is hidden within the clue.
'lorac' can be found hidden inside 'chapel or a church'.
'lorac' back-to-front is 'CAROL'.
'making' is the link.
(Other definitions for carol that I've seen before include "Religious song - girl's name" , "Joyful religious song" , "A traditional Christmas song or hymn" , "Joyful song - woman's name" , "and 27: Waits" .)
