In those days I did not distinguish between news and talk radio. I never listened to KEWB again after they flipped from Top-40. Got a couple of air checks of them around here somewhere though.Metromedia did not make KEWB all news. It was topical talk from those beautiful studios on Jack London Square in Oakland. But the format only lasted 3 years, going to standards, IIRC, in 1969.
I left the Bay Area in 1968 so wasn't around for the subsequent flip to Standards.
