Four who work and play together (7)
I believe the answer is:
quartet
'four' is the definition.
(synonyms)
'work and play together' is the wordplay.
I cannot quite understand how this works, but
'work' could be 'art' (I've seen this before) and 'art' is located in the answer.
This explanation may well be incorrect...
'who' is the link.
Can you help me to learn more?
(Other definitions for quartet that I've seen before include "Set of four people" , "Stringed group" , "film" , "Players" , "Group of four performers" .)
