SFA, it sounds like the name of the village Pwlldu is pronounced Poolf-dee? And the people do NOT want to leave...they have no bath, and must boil water for drinking, and she says it is healthier there! Although, I think her point was that Pwlldu is up higher, and the air is better fresher than the lowland place they were moving to?
I went to the YouTube link and copied the description the posters made, so people could see it, it's interesting:
"In 1963 the small hamlet of Pwlldu, near Blaenavon, was demolished. Originally a mining community, the mines had long since closed, and houses had fallen into a dilapidated state of repair, with no access to either running water or a sewerage system.
"The council took the decision to move residents down the valley to another village. Interviews with residents, one who had lived in the hamlet for over 70 years, show that even though conditions were harsh, not all wanted to leave.
"The foundations of the houses can still be seen, and The Lamb Inn seen in the film is still open today.
An interesting feature of Pwlldu is the 'Pwlldu Tunnel' which runs from Pwlldu to Blaenavon through the hillside. The tunnel was originally created in the late 18th Century and was one of a number of mines supplying iron and coal to Blaenavon Ironworks. In later years it was used as a tramroad tunnel.
Story has it that the ladies of Pwlldu used to walk through the tunnel to do their shopping in Blaenavon!"
