Well, there was "Brian Patrick and The Wake Up Crew" around 1989 (when I've first heard G105 via DX from Columbia, SC). Then, the show wound up as Brian & Kathy (Cruz) in late 89 to 1990, then my memory gets fuzzy until Bob & Mike's arrived from KHFI/Austin around September of 1991. I don't think G had a memorable morning show between the John Van Pelt era and Bob & Mike. Didn't John Van Pelt bolt from G to do mornings at 94Z when they've signed on?
