It's for Carling lager, marketed under the catch title 'Belong'. The ad is brilliant with its take on being stiff upper lip British in adversity, in the manner of Scott the polar adventurer (shades of Captain Oates who was going out and 'might be some time)',its background music of Elgar, and its great final line, when one bloke sticks his head into the blizzard and says 'It's brightening up !' .
Could someone tell me if I'm right here - I think one of the guys in the ad is Bruce Parry who is in the Tribe series of programmes. I say its definately him but my son says it's not.
