Remember when you marveled at how your grandparents and parents could recall in detail things that happened many, many decades ago? Granny told me exactly how she met Grandpa more than 50 years earlier. I was amazed. Then there are the Beatles on a recent television special, showing them performing on “The Ed Sullivan Show” 50 years ago. No way. Yes, it is true. It’s been a half-century, and I remember it well.
