Chilliwack are a Canadian rock band that had their heyday during the 1970s and 1980s. They are perhaps best remembered for their three biggest songs "My Girl (Gone Gone Gone)", "I Believe" and "Whatcha Gonna Do." While the members have changed Chilliwack is still out touring Canada from coast to coast. The band initially formed as the Classics (1964) in Vancouver, British Columbia, but later changed the name to the Collectors (1966). Their psychedelic debut album yielded the minor but long-remembered hit 'Lydia Purple'.
