I used to work those hours, and the early morning radio shows can be real helpful for folks that do. Ray Briem did the midnight to five am show for many years on KABC. He and George Putnam were the first two to take Clinton to the wood shed in 1991. They pegged that guy right out of the box.
Ray Briem was a good host and Putnam was a guy I wished I had listened to more.
Before the internet I was confined to ancient means of communication.
Briem actually got some hours on ABC Talknet so I could hear him in the East when that network existed years ago.
