What about the Bank holiday World of sport on Monday which of course is a LWT programme?
Normally, Dickie Davies would decamp to Thames Euston on Bank Holiday Mondays etc, and the programme was produced there.
The only exceptions were World Cup and Olympic games coverage where either LWT or Thames would produce the coverage 7 days a week. Of course such programmes were LWT or Thames productions 'on the behalf of the ITV network'
I seem to remember hearing that on one occasion that trailers shown during the week for a Mr Bean repeat scheduled for Friday night on LWT said that Mr Bean was on Friday night "on Thames" when of course that wasn't strictly true.
There's a point, did Thames/LWT trail each other's schedules?, did Thames advertise weekend shows as being "on ITV" or just pretend that weekends didn't exist?
On the Morecambe and Wise point. I don't think it was a rule, more that as it was Thames's biggest show, it wouldn't make sense for it to air on LWT.
ISTR that repeats of the LWT series Adventures of Black Beauty were shown at 5.15pm on a Monday in the early 80s on Tyne Tees. Probably scheduled locally by themselves or YTV (a fair bit of sharing went on in the Trident years). Not sure where that leaves the 'rule' as such. I do recall that Tyne Tees tended not to show the LWT frontcap in full, just a still - but that could be how the series was produced or re-edited.

There were plenty of instances of Thames and LWT progs being shown 'out of hours' by the other ITV companies.
There was no "rule". (If there had been, whose rule would it have been?) ITV programming was scheduled by each individual contractor with final approval from the ITA/IBA. As MarkyMark says, Thames and LWT programmes were often scheduled by other companies on the 'wrong' days of the week - as indeed ABC and Rediffusion programmes had been before. Thames and LWT were of course set up by the IBA to be rivals - rivals for the advertising income in London. They obviously couldn;t be rivals for audiences as they essentially shared the same audience. But each wanted to have more pairs of eyes watching their part of the week tnan were watching during their rival's days. So naturally, Thames wouldn't have sold Morecambe & Wise to LWT. That would have made no sense at all. However of course both companies sat on a variety of programming committees and co-operated in a numnber of ways. Daft notions about 'bans' are the kind of simplistic illusions the tabloids like to propagate.
Another point about ITV contractors programmes on Channel 4, all of them had their end boards with their normal logo. In some cases, such as Tyne Tees and LWT, their logo was a bit smaller, but the end boards were the same as on ITV, except with the additional line "for channel 4". However, Thames had a different end board in the 1980s for their productions on 4. Although there were two different designs, both had the same lettering as the normal ident for the word "THAMES", but the skyline was a silhouette. Why the difference for the end boards for their productions for channel 4?
Looking on TV-ark at some end boards for both LWT and Thames, I saw some of them said "An LWT/Thames production for Channel 4". I do know that Thames produced programmes couldn't be shown on ITV when LWT was transmitting, from 17:15 on a Friday until 05:59:59 on a Monday, and LWT programmes couldn't be shown when Thames had the transmission time.
This was shown up in embarrassing fashion for Morecambe and Wise, when they left the BBC for Thames, because this meant if Christmas day fell on a Friday, Saturday or Sunday, their show couldn't go out on the big night.
But, what if the programme made by Thames or LWT was commissioned for Channel 4? Could a Thames produced show, such as For what it's worth, be shown at 20:30 on a Friday evening on Channel 4, when LWT had the transmission time on ITV? Likewise, could that mean that an LWT produced show for Channel 4 could be shown on a Tuesday evening?
It did not matter about who made progarmmes on ITV for Channel 4. In those days if an ITV station were commissioned to make shows they also played out the advertising as it was all ads were transmitted locally.
They were therefore paid to make the show after bidding for it and took the split the revenue with Ch4.
There were plenty of instances of Thames and LWT progs being shown 'out of hours' by the other ITV companies.
Indeed, I've got a copy of the TV Times from 1981 where HTV are showing The Jim Davidson Show on a Sunday, and also one from 1983 where seemingly every region, apart from Thames presumably, were showing an LWT-produced birthday tribute to Larry Grayson (I think it was a Six O'Clock Show special re-redited for network consumption) on a Thursday. And 4 showed Thames and LWT productions on any day, Citizen 2000 was a Thames production and that was usually shown at the weekend.
As Tony points out, there was no rule Morecambe and Wise couldn't be on at the weekend, but obviously LWT wanted their programmes to go out on Christmas Day if it fell at a weekend, putting a Thames programme pride of place on a weekend would have been an admission all LWT's programmes were crap. And there was no great need to put Eric and Ern on Christmas Day after 1981 as they were going down the dumper a bit. They probably rated a bit better on the other days anyway, there was less competition.
