Digby linked to Do They Know It's Christmas - the original version, not any of the subsequent remakes - and I have to include it here because it's the first time that I can remember that I've seen the promo with the credits.
Note: "Film Lighting Services". That was Bruce's company. There was a very brief period in the early 80s when Bruce would come home and say things like "here's some random Madness swag" and "Our House, in the middle of our street, liars - we filmed it in a corner shop", and then we moved to France, he had a heart bypass operation and sold up; but for a while, Bruce was one of the people who mattered in the UK film industry. You could rely on him showing up on time and with the right gear - and probably a bit extra, because he knew that chances are you'd need that extra lamp even if you didn't think you would originally, and he was all about doing things properly.
So yeah. "Do they know it's Christmas," the promo. (Bruce always referred to what other people would call music videos as promos, partly because it was the industry term but mostly because they were often shot on film.) My dad shotlit that.
