Can't see him lasting very long on the coach, feel sorry for his wife - he was the same in the restaurant programme (there's quite a few people who pop up on more than one of these real life programmes, must be gluttons for punishment).
You should be able to watch it on catch up or whatever Sky calls it. It will certainly be on 4OD so you can watch it online and I think C4 has a 4+24 station so you could watch it tomorrow.
I watch it early evening - the kids are still milling about so I don't watch anything that I need to concentrate on. I don't get why people watch sport or history programmes (or lots of other stuff actually). Each to his/her own. Find it quite interesting that people question why people watch this sort of thing or soaps, but not 'intellectual' programmes.
