My main interest in these tv plays is as period pieces, watching out for old fashion, hair, shops, tv's, furniture, decor, that sort of thing.
Abigail's Party was on this wednesday on BBC4, (I think). There's a brief shot of their telly, on a trendy 1-leg stand, surprised no one's mentioned it!
I agree the camera work/VT recording is of a high standard, quite normal for that period, from memory, although you see the odd shadow of a boom mic from time to time (also quite normal for the period!!).
There's also a bit of comet-tailing from Beverly's jewellery.
