While the Guess Who did have several hits in America, they were superstars in their home country of Canada during the 1960s and early '70s. The band grew out of vocalist/guitarist Chad Allan (born Allan Kobel) and guitarist Randy Bachman's Winnipeg-based group Chad Allan and the Expressions, originally known as first the Silvertones and then the Reflections. The remainder of the lineup featured bassist Jim Kale, pianist Bob Ashley, and drummer Garry Peterson.
