If anyone's interested - it's not gone above zero here in Strasbourg since I got back, heavy snow and wind shut the trams down for a bit on Friday night, and everyone's just getting on with their lives. It doesn't, however, stop me cursing the security guard at work's name up and down when he won't open the building at 7h45 instead of 8h. Grr.
Looks like you're right, but that's not the context in which I remember it. It's definitely in black and white in my memory. [IS,P] Did you spend any time in South Africa?
Whoever sang it, I would love to teach it to the people of France. However I've yet to find a good translation for "jobsworth". But yes, people are just dealing with the cold - the phrase "Keep Calm and Carry On" seems apposite.
