That one of Sergeant Pepper's was stopped from playing.
I remember being astounded, much more than upset at Lennon's murder. It seemed so odd. The decade of shootings seemed to be the 60s and they were political not a pop star. At 16 I was ambivalent about Lennon, much of the more unpleasant stuff was only hinted at, I hated Imagine (still do), but I liked his books.
The same day the BBC showed one of my favourite 'plays' in Play for Today, The Flipside of Dominic Hyde. As a time traveller, he came back from a future where the classical music, played by holograms was The Beatles. Then seemed fitting, now I see that time has odd unfathomable effects and it moves faster, not just because of my ageing.
As with all times, it always feels to me that Dickens got it right in the opening to A Tale of Two Cities.
