I can also think of a certain Irish language magazine programme I transmitted once, which was being assembled live in the edit suite... They were even typing up the in vision English subtitles as they were going along. It came off air to the exact second that the editor told me it would. Talented guy.
On the day of the BBC power cut in 2000, which of course was also the day England went out of Euro 2000, there was a special Panorama planned about hooliganism, and I had the issue of Aerial from that week which said that when TV Centre lost power, Panorama had to find an edit suite in Belgium at the last minute and do everything from there in a matter of hours, including pixelating faces, adding subtitles and changing the voice-over to reflect England's exit.
To quote from another book, Will Wyatt says that when he started working in Presentation Programmes, although he wasn't going to be working on the actual transmission side, as part of his training he had to run BBC2 one night. He was quite enjoying it, picking up the phone to tell the news that they were going to be on time and all that, and then when Gardeners World came on the producer phoned up and said they'd got the wrong take and any minute now it was going to stop. And the second he put the phone down, it did.
Actually in The Book Of Heroic Failures, which I used to love, there's a bit about a Miss Yorkshire Television where they accidentally transmitted the wrong take and so the show began with Tony Monopoly walking on stage, messing up his opening link, going off and coming back on again.
On many entertainment shows the presenters are on switched talkback too - but there are a few notable exceptions. One or two work on open, others won't wear talkback at all.
I know Mike Read didn't wear talkback on Saturday SuperStore, seemingly much to the irritation of the production team. Actually there's most of an episode of the first series of SuperStore on YouTube and it's a total shambles, it must have been a real shock for the producers to go from the unflappable Noel to the hapless Read. And Mark Curry points out in the Blue Peter anniversary book that the presenters first got earpieces when he was there, alongside autocue.
I think it was in a documentary showing a whole day in TV that showed Mike Scott totally screw up the end of an episode of The Time The Place because he couldn't work with an earpiece, and ended up falling off air because he wasn't watching the Floor Manager's cue.
That perhaps wouldn't be so surprising because I remember reading at the time that Scott had to leave The Time The Place because he was going totally deaf.
There was still c.5 minutes until off-air (perhaps longer), and Tess was supposed to interview some of the couples (getting their reaction to this unexpected twist) to fill time, but Bruce started reading the closing link off the autocue straight off the back of the shock announcement. He wasn't able to be stopped, and the SCD production team just ran the credits early and came off air about 5 minutes early, leaving presentation with a hole to fill.
I love the idea of Brucie being totally unstoppable. You can hardly blame him for everything that went on that night, anyway, it was a bit of a shambles all round. That said, I do know that when Brucie was presenting the TV Times Awards in the early eighties he forgot the final award and started saying goodbye too early, much to the confusion of Robert Mitchum who was waiting to come on. But he remembered halfway through and tried to make it look like he'd meant to do that.
