This could be Eccles High Street (6)
I believe the answer is:
setter
'this could be eccles' is the definition.
The definition suggests a singular noun which matches the answer.
'high street' is the wordplay.
'high' is an anagram indicator (can mean drunk or on drugs and hence disordered).
'street' is an anagram of 'SETTER'.
Can you help me to learn more?
(Other definitions for setter that I've seen before include "Red - - , dog" , "Jelly, perhaps" , "Street (anag.)" , "Breed of dog - crossword compiler" , "cement, perhaps?" .)
