Guitar Johnny & the Rhythm Rockers was a group more famous for who was in their ranks than the scant bit of recorded music they made. Formed in Boston in the late 1970s, they were led by guitarist-singer John Nicholas, who would later spend several years working in Asleep at the Wheel. The bassist was Sarah Brown, now noted as perhaps the most in demand session bass player in the blues and roots music field and a songwriter of considerable note. The drummer was Fran Christina, who would move on to Roomful of Blues and eventually the Fabulous Thunderbirds in their hit making days. Blowing tenor was Mark "Kaz" Kazanoff, later going on to making a name for himself on the Austin, Texas music scene. The rhythm guitarist was none other than Ronnie Earl (Horvath), who later went on to a stint with Roomful before forming his own instrumental outfit, Ronnie Earl and the Broadcasters. Strictly a local phenomena in the Boston area, the group only left behind a four song 45 rpm EP on the now defunct Baron label that featured a couple of Nicholas originals and a vocal from Sarah Brown. They would all soon move on to bigger and better things.
