The old man meeting unhappy woman in US city (8)
I believe the answer is:
pasadena
'us city' is the definition.
(I've seen this before)
'the old man meeting unhappy woman' is the wordplay.
'the old man' becomes 'pa' (both can mean father).
'meeting' says to put letters next to each other.
'unhappy' becomes 'sad' (synonyms).
'woman' becomes 'ena' (feminine given name).
'pa'+'sad'+'ena'='PASADENA'
'in' is the link.
(Other definitions for pasadena that I've seen before include "US city" , "Californian city" , "city in 23 [CALIFORNIA]" , "California city of the Rose Bowl stadium" , "LA neighbour" .)
