A. Chilliwack is a Canadian rock band centered on the singer and guitarist Bill Henderson, which started off with a more progressive rock sound that incorporated elements of folk, jazz and blues, before moving towards a more straight-ahead hard rock/pop rock sound by the mid-70s. They were active from 1970 to 1988. Henderson reformed the band in 1997. Their six best-selling songs were “My Girl (Gone, Gone, Gone)”, “I Believe”, “Whatcha Gonna Do”, “Fly At Night”, “Crazy Talk”, and “Lonesome Mary”.
The band originated in Vancouver from members of the C-FUN Classics that changed the band’s name to The Collectors when Bill Henderson joined in 1966. Their psychedelic self-titled debut album yielded the minor hit “Lydia Purple”. Their second album was based on the musical score written by the band for a stage play by Canadian playwright George Ryga, Grass and Wild Strawberries.
Vocalist Howie Vickers left the Collectors in 1969; the remaining members formed the band Chilliwack in 1970, Chilliwack being a Salish term meaning “valley of many streams” and the name of a city east of Vancouver in the Fraser River valley.
