I hope I'm asking this in the right place.
WBT Charlotte NC was probably a full-service MOR station before it switched to Top 40 and made a lot of people mad. However, the format was usually described as "adult contemporary" after a year or so had passed. Still enough of a difference that we couldn't say that MOR became adult contemporary (despite Broadcasting Yearbook's definition of MOR).
I did see a list of artists played on WBT before the change that resembled what would later be called "adult standards".
