For Those About To Talk: As tipped yesterday (CAT 5/23), Cumulus' WZRR/Birmingham has flipped to Talk. The station was Country as Nash Icon until last Friday (5/20) when it stunted as a Country/Classic Rock hybrid called The South. After PD/afternoon personality Peter "Z" Zolnowski, whose exit we reported yesterday, middayer Valerie Vining was the only other local talent. She remains as the cluster's Dir./News.
