On the assumption that none of the other nations had a similar screw up, you have to assume they cut to the wrong clean feed, but you have to wonder how. There seems to be little reason to have that feed available since the closure of BBC Two Scotland, unless it was an accident involving the switchable clean feed circuit.
Could have been a switching error at the other end of the line, so from London?

For the first year or two of BBC Scotland it simulcast BBC Two programmes in the afternoon. Even without those it's still useful to have BBC Two fed up to them and available in playout.

It’s something of a coincidence that the BBC Two programme was scheduled to start only a few seconds after Comic Relief on BBC One. Not exactly unusual, but scheduling wise it’s rare for programmes except news to start bang on the advertised time and it’s more common for the BBC One programme to start 30 seconds or so before or after the BBC Two show, despite both being advertised to start on the hour. Had there not been this coincidence, we may have seen the BBC screensaver/placeholder graphic from the clean feed.
THE NEXT POST FOLLOWS SHORTLY…

I wonder if the fact that both One and Two clean feeds would have been on the same animated filler contributed to the cockup? Maybe having something on the animation to ident which feed it is would have helped.

This one here, from the Saturday morning kids show "Motormouth", is interesting. Three things make it interesting. Firstly, it's a TVS show, so is therefore TVS networking it, but secondly, the colour bars are from HTV, no idea if Bristol or Cardiff, and lastly, this recording is from the LWT region. How did it end up with HTV colour bars, on LWT on a TVS show?

A programme from TVS Maidstone going to air via TVS Southampton pres and a BT switch going awry?

That's a possibility Steve. I forgot Motormouth was made in Maidstone, not Southampton, so it's feasible that it was being recorded live in Maidstone, but then being sent down the line to Southampton, before transmitting to the network.

It could be that it was just an accidental switch of the BT circuit into LWT (and possibly everyone else) - so suddenly the one from Maidstone becomes one from Cardiff or Bristol.
Alternatively, it was a mistake in LWTs lines room. Someone routing another incoming circuit (or a VT that just so happened to have HTV bars on it) onto the OS line into the TX suite that had Motormouth on it. The fact it was a clean sync cut between the two and it was resolved fairly quickly make this seem the more likely scenario

All main incoming circuits to the South Bank had synchronisers on them so a clean cut between the two different external sources would not in itself mean too much I think. The short period of black between the two sources however would indicate to me a synchroniser sensing a momentary loss of incoming signal and outputting black (a standard synchroniser’s user setting) and then reinstating the output once the next stable source came along - whatever it was.
I would guess Maidstone into SB via BT tower for networking via LWT (TVS being the originating company). I would have to consult my old IBA routing maps but I’m pretty confident Bristol was direct to BT tower and unless a Bristol circuit was required at SB on a Saturday morning perhaps we would be looking at a BT tower switching error? The length of the ‘fault’ would seem typical of a switching fault, SB immediately noticing, buzzing BT to tell them of the error and BT correcting it.
But of course as is so often the case we will never know.
PS. Circuits into SB were known by their individual KRS numbers, these were then assigned as ‘Remotes’ (Rem 1,2 or 3 etc) for internal distribution around the technical areas, ‘OS’ was not terminology used by LWT although I understand why you have used it - I only mention it just for info.

When you say buzzing BT, do you mean phone them or was there a 4 wire or similar to them?
If the former it seems a bit quick. Mind you I remember a programme overrunning and being derouted by the Tower and the engineer on duty taking it upon himself to put it back as he was watching it off-air and wanted to see the end
