The surprising thing in the article to me, is that Clark has announced he's retiring. It sounds like he's really walking away from all of it. From Feder's piece...
Weber said his last radio interview will be May 19 with midday hosts Bob Sirott and Marianne Murciano on Tribune Media news/talk WGN AM 720. His last speaking appearance will be May 22 at Chestnut Square Retirement Community in Glenview. Then he’ll take one last bow at his June 16 Hall of Fame induction.
I worked in the same hallway as Clark for several years when I was with John Landecker's show at WJMK and Clark was hosting the morning show at WJJD. I always enjoyed chatting with him. He has some incredible stories. If you ever get a chance to read his book, there are a bunch of stories in there.
He told some more (including the story of introducing the Beatles at Comiskey Park) when I interviewed him a few years ago for Chicago Radio Spotlight.
