Formal interview (8)
I believe the answer is:
audience
'formal interview' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for audience that I've seen before include "They've come to see a play" , "which may be given an address" , "House" , "Assembly gathered to watch, say, a play" , "that might come into play?" .)
