I just found out about this one, surfing the dial. To my surprise WNIC in Detroit has picked up American Top 40 the 80s with Casey Kasem. This is the first time WNIC has aired AT40 the 80s. Thus, Casey will remain on WNIC. It airs Sunday nights from 8pm to Midnight on WNIC from January through October only. They even have Casey liners with him saying, "Thank you for flashbacking with me on 100.3 WNIC."
I checked WLVG for Sunday night, 7/12. They are only playing their regular music.
It looks like WNIC is not airing Hour 1 of AT40: The 80s. The 8pm hour shows regular music, and Hour 2 began in the 9pm hour. As far as I know, this is the only station that omits the optional Hour 1. Still, I'll take it if the show gets another affiliate.
WQMA has added "American Top 40: The 70's" to replace AT10 immediately following the "National Countdown Show with Al Gross". The two shows should complement each other very well since Al's show focuses on a top 40 countdown from the the 50's and 60's.
"National Countdown Show" starts at 9am, and "AT40: The 70's" right after that at 1pm.
