23/02/1984 - ITV - Afternoon Plus (HRH Duke of Edinburgh) 

Complete with Tom Edwards in-vision continuity from Thames, here's a full episode of Afternoon Plus (now titled A-Plus) from February 1984 which features the Duke of Edinburgh in discussion with Gill Nevill. After this, there's a promo for the following day's TV-am (25 minutes of which I found here a few years back: • 24/02/1984 - ITV - TV-am ) and then a quick Thames slide for Crown Court.
