Anyone remember Wolfman jack? I used to listen to him broadcast out of Del Rio, Texas - XERB was the station, but it was in Mexico. He would talk thru the first 20 seconds of whatever song he played and talk again thru the last 30 seconds. Also sell chickens, etc etc. You'd finally get fed up with him and switch to KOMA in Okla City. I was stationed in Roswell, NM from 1964-67, so KOMA was better than the local stations. All AM of course.
