The live interview was already disrupted when they started interviewing a random person as an expert. Everyone watching being misled, to me, is a bigger disruption to the interview than admitting something is wrong. IMO the best thing to say is something along the lines of "I think there's been a bit of a mix-up, I'm not the person you think I am, but if you want my two cents anyway ... ". Obviously in reality I would've fumbled worse than this guy did, its easy to think things through with the benefit of not having the pressure of being put on the spot on live TV.
