Vocalist, keyboardist, and guitarist Chad Allen and guitarist Randy Bachman first worked together in bands like the Reflections and Chad Allen and the Expressions. In 1963, they decided to form another little rock group -- they became the famed Guess Who. By 1970, though the Guess Who were still alive and kicking, Bachman and Allen turned their attention to a new rock outlet, Brave Belt. Other members were bassist and vocalist Fred Turner and drummer Robin Bachman. After the completion of one album, and only a little work on a second, Allen left, and was replaced by guitarist Tim Bachman. Before a third offering was ready, Brave Belt folded into a new mortality, Bachman Turner Overdrive.
