An audience for bingo? (5)
I believe the answer is:
house
I believe this clue is a double definition.
'an audience' is the first definition.
(term for a theatre's audience)
'bingo?' is the second definition.
(another word for bingo in the game bingo)
'for' acts as a link.
(Other definitions for house that I've seen before include "Provide with shelter" , "See 13" , "Dwelling or official assembly" , "Firm; home" , "Dwelling, living quarters (5)" .)
