I'm going to dispute that first sentence, specifically the word "demote". Bill's now in his 70's. He still sounds good, but that could change in the next few years. He may no longer want to shlep into lower Manhattan to do a live show five days a week. By shifting to evenings, that offers him and the station a few new options: (a) voice track some of those shows and only be live in studio 2 or 3 times a week, or (b) voice track all five shows each week from a home studio, or even (c) do all five shows live but remote from the home studio. (Pat St. John used to do some of his weekend shows this way when he was on CBS-FM, and still is remote on SiriusXM.) In exchange for the added flexibility, he might be taking less money, allowing CBS-FM to lower their talent budget. This could be a win-win for both parties, and the station keeps a popular and respected talent a while longer.
