company booze-up under discussion: .e.y

Bevy - also being a company of various sorts of birds

The clue is intended to be read as:
company = bevy which sounds like (under discussion) bevvy (= booze).
But Chambers gives both bevy and bevvy for the second meaning so some of the wording's a bit redundant.
