Music where woman’s parts reversed? (7,3,7)
I believe the answer is:
country and western
'music' is the definition.
(country and western is a kind of music)
'woman's parts reversed?' is the wordplay.
I cannot quite see how this works, but
'woman' could be 'ester' and 'ester' is found within the answer.
This explanation may well be incorrect...
'where' acts as a link.
(Other definitions for country and western that I've seen before include "American music genre" , "Style of popular music" .)
