Following the news that my mother had been diagnosed with pancreatic cancer last March, I recently re-watched Potter's Cold Lazarus, one of a pair of plays he wrote after receiving his own, similar news.
I read a lot into Cold Lazarus that, as it turned out, Potter doesn't seem to have intended. My mother's lucidity began failing pretty quickly and she increasingly slipped into bouts of confusion - mixing memories, dreams and the present to inform her reality - that have now, sadly become her normal state of being. I mistakenly related this to the visions the Lazarus scientists elicit from Daniel Feeld's frozen head. These thoughts led me to Potter's last interview, with Melvyn Bragg, only months before his death in 1994. He was anything but confused.
Many of you will probably have seen this previously. It's a great interview but the moments from about 24 mins in particular are relevant to this forum.
