I was just searching on a different Beatles topic when Google, as usual, popped up with its list of "similar searches" (which are usuall side-splittingly funny). One was "Who is the biggest Beatles fan?" so of course I had to click to see what came up: Kolya Vasin.
https://en.wikipedia.org/wiki/Kolya_VasinI have the feeling I am going to be the only one here who has never before heard of Vasin. Perhaps I have read about him and simply forgotten.
It seemed to me like he had a bit of a sad life, and indeed he committed suicide in 2018.
Anyway, just in case I'm NOT the only one who wasn't familiar with him, I thought I'd post the Wikipedia link.
