Help got by Skyfall singer in city (8)
I believe the answer is:
adelaide
'city' is the definition.
(Adelaide is an example)
'help got by skyfall singer' is the wordplay.
'help' becomes 'aid' (synonyms).
'got by' is an insertion indicator.
'skyfall singer' becomes 'adele' (Adele released the song Skyfall).
'aid' inserted inside 'adele' is 'ADELAIDE'.
'in' is the link.
(Other definitions for adelaide that I've seen before include "town" , "Australian location" , "Antipodean city" , "port in Oz" , "Australian capital" .)
