Diana still performs today, a few times a year.
It has to be difficult to become anonymous when she’s not onstage or around show people. Diana probably lines up in LA grocery stores standing right in front of junior high school kids who don’t recognize her. Some might recognize her, but don’t care. They might tell their grandmothers who they saw.
Maybe.
All fame is fleeting. I recall when I realized some people ‘didn’t know’ who The Beatles were. Worse still, they knew but didn’t care. I could have fallen out of my chair in shock and disbelief.
I'm not the least bit surprised that such people exist. A friend of mine graduated from Hollywood High School in Hollywood, Calif. in the mid-sixties. The school (and the home where he grew up) is mere blocks from major mass media institutions. Yet he had never even heard of the Beach Boys until around 1970, long past their peak hitmaking years. He was a fan of Adult Contemporary music--Frank Sinatra, Peggy Lee, Connie Francis, etc.- and listened to stations like KPOL and KFI, which featured that sort of programming.
As for me, I was a fan of KWIZ, which featured "oldies" and some current Adult Contemporary fare, and I never even heard the Beatles' hit "Hey, Jude" until long after it had dropped off the charts.
