BBC4 - Saturday Night TV Season

[Neil Jones]

Let's see how badly they edit out the phone numbers that presumably wouldn't work anyway. Hopefully a simple graphic advising people they'd be stupid to call a TV show made 30 years ago will suffice.

This is BBC Four, an audience that is smart enough to realise its a 30 year old programme. Its not like ITV where you have to put a disclaimer on the graphics and spell it out even for +1.
And 0891/0898 numbers haven't worked since the 1990s after the so-called PhONEday system, but I don't think those were reallocated.
