I was not majuberized, but am curious what years he did this. I remember Jazzbeaux from later years- playing music, but never on KGO.
I'm wondering also if this was a common radio bit. In LA in the mid 60s thru about the early 70s - Robert W. Morgan would "Morganize" a caller on his KHJ radio show. It was just a weird sound effect and he'd say, "Zap - you've been Morganized!" Then they'd play his jock jingle. It was kind of lame, actually.
On his TV show (Groovy!), he'd put a teen girl in a glass booth to Morganize them. They would always come out laughing and looking embarrassed. We always figured the girls were getting air shot up their dresses or something...but we were horny teen boys, so who knew?
