Old Radio Show

A number of years ago there was a real good Automotive question and answer show on the radio. I belive the guy who did it was named Jeff Smith. His theme song for the show was On The Road Again (I think). My local station quit carrying him when he switched satalites carrying his show. It was a live call-in show on saturday mornings. Anybody know what I'm talking about? Is he still on the air? I tried looking for him on Google, but found nothing.
