Demand work for the audience (4)
I believe the answer is:
need
'demand' is the definition.
(synonyms)
'work for the audience' is the wordplay.
'work' becomes 'knead' (synonyms).
'for the audience' shows a homophone (sound like) (how an audience might hear it).
'knead' sounds like 'NEED'.
(Other definitions for need that I've seen before include "Cry out for - prerequisite" , "state requiring relief" , "Necessitate" , "destitute state" , "must have results!" .)
