Harry's dead. Bill's dead. Don and Ron and two of the four Dans are dead. ("Bob Shannon" is really Don Bombard, and he retired for health reasons over a decade ago.) Bobby's up there in years, and Dan Taylor is getting there. You didn't mention Bruce, but he's 85 or so. The iconic deejays are either quite old or no longer with us.
I enjoy a lot of that musical era, I grew up with it, and as it happens one of the aforementioned guys was a friend, and I've met a few of the others over the years. I used to love that station. But "Rock Around the Clock" debuted in 1955. (As it happens, so did my brother, and they're now both 67.) When CBS-FM launched as an oldies station in 1972, "Rock Around the Clock" was 18 years ago, and everything else they played was more recent. By 2005, when CBS-FM got Jack'ed, it was half a century old. So if you had just entered junior high when it hit #1, you were 62 or 63 by then. Sadly, advertisers don't want to spend money to reach you, and stations need revenue to stay viable, so the music of your youth ain't gonna cut it any longer. That's the way it works, whether you (or I) like it or not.
