Yesterday, a radio personality said that when he was younger, his dad and he would listen to an oldies station, and his dad would quiz him about who sang particular songs; typically, they were by The Dave Clark Five. As the announcer observed, however, most oldies stations don't play bands like The Dave Clark Five as much these days. He said that most oldies stations are more likely to play a band such as Hootie & The Blowfish.
He's right. It's an adjustment to realize that, as you age, society's definition of songs that qualify as oldies changes. When I started listening to the "Super Oldies Show" on KXOK in 1979, most of the oldies had been hits before I was born, and the remainder of them were hits before I started school. Today, the radio industry's definition of oldies includes a great many songs that were hits after I graduated from college.
Do I feel ancient? No. I sure feel older, though.
