When I saw the obit in the paper, I recognized her name only because of the Pink Floyd song noted above, and I was surprised to find that said song's lyrics "We will meet again some sunny day" were song title references. I didn't know Vera Lynn was a real person until I saw the reports of her death.
Also, if you ever saw the film
Dr Strangelove,
'We'll Meet Again' (in Vera Lynn's original) was played over a series of nuclear bomb explosions in the film's finale.
I did remember the Pink Floyd track referenced above (I have the album).
