Respect pop singer's shown for old city, a capital (8)
I believe the answer is:
honolulu
'capital' is the definition.
(state capital of Hawaii)
'respect pop singer's shown for old city a' is the wordplay.
I cannot really understand how this works, but
'old' could be 'o' (common abbreviation eg in OE for Old English) and 'o' is present in the answer.
'singer' could be 'lulu' (Scottish singer born 1948) and 'lulu' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for honolulu that I've seen before include "Hawaii's capital" , "Port in Hawaii" , "City of Hawaii" , "Hawaiian capital" , "island capital" .)
