I saw the Beatles live in San Diego in '65. It was at the height of Beatlemania. They proceeded to get more creative and important. Of course by '80 they had been broken up a while, but there was always a possibility they could have a reunion. Groups do that all the time. I'm in SoCal and on that day I was on a business trip in Chicago, when I heard the news (today oh boy). I obviously didn't know him personally, but it did affect me. I guess I realized that that period of time, and my life, was really gone and couldn't ever come back.
I recently saw "Love" the Cirque du Soleil Beatles themed production in Las Vegas. It was really good, and frankly the whole story and music moved me still.
