Guys, I've figured it out. I have figured out how Casey was able to do three shows at once. All the Requests and Dedications were the same, as well as Casey's Concert Calendar. All that needed to be swapped in and out were the charts and extras.
I remembered on a few rare moments, you would hear Casey on Casey's Hot 20 telling you to write them at Casey's Top 40 instead of Casey's Hot 20.
Thinking that may have been a production error...I'm sure that's happened a few times. I have many CH20 shows in my collection, but haven't heard most of them yet. The ones I have heard, I didn't notice any errors like that. I'm sure there's several instances.
David Perry did introduce us to Casey's Hot 40 once... 😂
Well yeah, it wouldn't make sense to record content that was the same.
He also was able to record three shows a week because, well, it's still not that much content compared to air personalities that do a daily show five or six days a week. Especially since it was all prewritten for him when he came in.
