Chilliwack were formerly a band called The Collectors with lps on 
Warner/Reprise back in the late 60s (their live highlight was a song 
called "Rain-O" and their hit was "Lydia Purple"). I remember seeing 
them (Collectors) on a TV show when I was a kid and very duly 
impressed.

Main guy Bill Henderson has had a very very active career and one of 
his daughters was in a pop band
called The West End Girls

I think every once in a while a permutation of the band hits the road
