There was a special on PBS.
The topic was Winston Churchill and it was narrated by his granddaughter.
From a cursory search, it must be Chasing Churchill. It is available on Amazon, I have put it on my wishlist so the next time I order, I will get it.I never saw the whole show.
I would watch for a tiny bit of time and her very soothing British accent would put me to sleep immediately.
My whole family was much amused by this falling to sleep thing.
It was highly effective on nights I could not sleep.
I used it for a very long time.
I should never have deleted it because it was so effective.
