Thanks to 623058 who provided me with these schedules for the Thursday and Friday following the strike, and gave me permission to share them here.
Thursday 25th October 1979:
Friday 26th October 1979:
Evidently these schedules are for the London area, but in answer to my queries earlier, it seems the only regional variations on the Thursday were the local news magazine and late night programming from 11.15pm (which may have just been a closedown in the smaller regions). I was wrong about the News at One not appearing on the Thursday, but it seems to have been a somewhat curtailed bulletin.
Friday was pretty much BAU - local news, Bible readings etc probably appeared prior to the 9.30am programme in some regions. The local news at 1.20 is back along with any other local content that often filled that spot (Lookaround, What’s On Where etc). Less variations than you would normally get in the afternoon and evening, I expect, but local again from 11.15pm.
There have been comments on TV-Ark’s Facebook page stating Westward Diary replaced The Muppets on the Wednesday - and that it may have even been shown earlier in the week. Not sure if that’s accurate info - in particular it seems unlikely Westward interrupted the blue screen of death earlier in the week for their local news. If they did show this on the Wednesday, they likely opted out of the trailers and pre-startup menu that advertised The Muppets.
Another rumour bouncing around over there is that Border didn’t come back on air until the following Monday “because they liked being on strike”. This I take with a very large pinch of salt, but I’m prepared to eat my words if necessary!
Was the Emmerdale Farm on there a repeat? As there weren't any new episodes between the 5th July 1979 and the 8th January 1980. Possibly Thames showing episodes out of sync with the network like they did with Crossroads for a while earlier in the 70s.
