“That’s one small step for man,” said Neil Armstrong, after touchdown on the Moon - and the rest makes a good question for our family Zoom quiz on Friday nights.

I was trying to remember it while we were watching an episode of UFO, the British science fiction TV series made in 1970.

Until we can get out more, my wife and I have developed a fondness for finding old programmes to watch, to the extent that “They don’t make ’em like that anymore” is now often the last thing we say to each other after turning out the bedroom light.

What’s notable about UFO is the great theme tune, the rubbish scripts, the frankly kinky uniforms worn by the female characters, the brilliant models - it was, after all, made by the great Gerry Anderson, of Thunderbirds fame - and all the smoking.

Almost every time they cut to a scene on Moonbase, their first line of defence against the invading aliens, it seems they are more interested in having a crafty fag than shooting down flying saucers. It prompted our daughter, who had never seen the programme before, to ask us: “Did everybody smoke, back then?”

In a way, we did.

It’s only 14 years since the smoking ban finally rescued non-smokers from smelling like ashtrays and being forced to breathe carcinogenic gas, but it takes a comment from somebody in their twenties to remind you of how much has changed in your lifetime.

Another programme they don’t make ’em like anymore is Perry Mason, which we have also discovered lurking in late-night slots on obscure cable channels.

That goes beyond nostalgia for us because it was made before we were born - starting in the late 1950s, when people smoked even more than they did when UFO was made.

We have come to love Perry Mason, even if the only thing in the world that’s more predictable is Celtic or Rangers winning the Scottish League. And I’m not just talking about the same plot being used for every episode, which is Perry proving his client is innocent by finding out who the real murderer was, and forcing them to confess in court.

Other certainties are the involvement of a pretty woman; blackmail, a bitter broken marriage; Perry’s assistant, Paul Drake, interrupting the hearing to produce a hitherto overlooked but vital piece of evidence; and most of the characters smoking like chimneys.

All this historical smoking got me Googling, and I came across the old footage of Mission Control helping Neil Armstrong down to the Moon, which is notable for two things.

Firstly, of course, there were no women - because when it came to men’s stuff, evidently Houston had a problem with mere females doing it. And the second thing is that everybody in Mission Control was a smoker, so the first thing they did after they got Apollo 11 on the moon was pass round the cigars and light up.

So there’s your answer: it was one giant leap for Benson & Hedges.
