I see that Freeview have compiled a list of people's most memorable TV moments.
The collapse of the twin towers comes top, ahead of the moon landings and Diana's funeral. At number five is Bob Geldof asking people to "give us your fucking money" during Live Aid.
It really is remarkable that this event looms so large in people's memories because it never happened. I know because I was there. Let me take this opportunity to place on record the true facts.
Geldof wanted Live Aid to be a fundraiser. The BBC didn't. There were details of how you could give money. You could send it by post, you could pay at a Post Office or you could ring up and pledge a donation. The captions came up in that order: address, PO details, phone number.
I was anchoring that part of the broadcast, up in the boiling hot perspex box in the roof of Wembley, and, following one of Geldof's finger-pointing rants, went to the appeals procedure.
"Here's the address," I said.
"Fuck the address," he said. That was quite a moment.
I've never looked at a tape of that incident since the day but I was amazed to watch the "give us your fucking money" myth blossom. People who had watched it told me with great certainty what had happened, as did people who hadn't.
When Mark Ellen was preparing a 20th anniversary piece for Word he spent a day going through a tape of the whole thing. I asked him to let me know what Geldof had actually said.
"Fuck the address," he reported back.
I was relieved that it was the world that was deluding itself and not me.
I was thinking about this this week when weatherman Michael Fish was on BBC News24 explaining the real story of his notorious hurricane forecast. It turns out that the hurricane he was referring to was a tropical cyclone in the West Atlantic. He told his story but you could tell from the expression on the interviewers face that they weren't remotely interested in the disappointing truth.
Every time I read somebody's memoirs or hear about somebody giving evidence in a courtroom about events that took place many years earlier, my thoughts turn to Live Aid and the things we are capable of "remembering".
