Besides tea houses, where might you encounter The Blues? (7)
I believe the answer is:
'where might you encounter the blues?' is the definition.
The definition suggests a singular noun which matches the answer.
'besides tea houses' is the wordplay.
'besides' becomes 'else' (I've seen this in another clue).
'tea' becomes 'cha' (cha is a type of tea).
'houses' indicates putting letters inside.
'else' placed within 'cha' is 'CHELSEA'.
Can you help me to learn more?
(Other definitions for chelsea that I've seen before include "Word linking boot and bun", "place of buns", "Hillary Clinton's daughter", "issue for Clintons", "The Blues of Stamford Bridge".)
