Geez. A bit of morbid news (be warned).
I'd looked up the Real Mrs Robinson show (guy went on dates with the mother and daughter) to find more about it.
Now I can't find many sources but it looks like the daughter was found hanged around a year after this aired and then 3 years later Tracey (the Mother) fell from the 10th floor of a block of flats.
It also looks like the scene with them was replayed in a "Best of TV Burp" episode in 2009 and ITV ended up pulling the footage.
