Chilliwack are a Canadian rock band that had their heyday during the 1970s and 1980s. They are perhaps best remembered for their five biggest songs "My Girl (Gone Gone Gone)", "I Believe", "Whatcha Gonna Do", "Fly At Night" and "Lonesome Mary". The band's lineup has changed numerous times, though Bill Henderson has constantly remained a fixture, and Chilliwack continue to tour across Canada.
