Their six best-selling songs were "My Girl (Gone, Gone, Gone)",[3] "I Believe", "Whatcha Gonna Do", "Fly at Night", "Crazy Talk" and "Lonesome Mary".

Their second album was based on the musical score written by the band for Grass and Wild Strawberries, a stage play by Canadian playwright George Ryga.

During 1970, Miller briefly left the band, who were joined on the road by Robbie King (keyboards, bass) and played at Expo '70 in Japan and other gigs across Canada.

In 1971 bassist Rick Kilburn played live with Chilliwack for a short time before Miller returned later that same year when Lawrence departed.

The album was re-recorded; with some of Froese's vocal and guitar work, as well as percussion from session drummer Eddie Tuduri, included in the final mix.

Drummer Skip Layton and former Prism bassist Ab Bryant were recruited to perform with Henderson, MacLeod and Jamie Bowers (guitar and keyboards, who had also played on Lights from the Valley) in Chilliwack's 1978 live gigs.

[11] Henderson, MacLeod and Bryant then began working on Chilliwack's eighth album in 1979, joined by John Roles (guitar, keyboards, backing vocals) and drummer Bucky Berger.

But a lack of consistency kept it from international success.Henderson, MacLeod and Bryant were joined by drummer Paul Delaney in the fall of 1981 through early 1982 for US promotional appearances on TV shows, like American Bandstand,[13] Solid Gold and The Merv Griffin Show, before heading out on the road later in 1982 with an expanded line-up of Henderson, MacLeod, Bryant, Joey Franco (drums), Glenn Grayson (keyboards, backing vocals) and Dennis Grayson (keyboards, backing vocals).

In early 1983, MacLeod and Bryant left the band to devote more time to their other project, the Headpins (with Denise McCann and then Darby Mills as lead vocalists).

He was joined by session players Ashley Mulford (guitar, backing vocals, from the band Sad Café), Richard Gibbs (keyboards, from the group Oingo Boingo), Mo Foster (bass), Simon Phillips (drums) and Tom Keenlyside (saxophone), with additional vocals provided by Mark LaFrance, Saffron & Camille Henderson, Dustin Keller and Bob Rock.

On October 6, 1991 Henderson joined fellow rockers Loverboy, Bryan Adams, Colin James and Chrissy Steele at a benefit show at Vancouver's 86 Street Music Hall to raise over $50,000 for Henderson's former Chilliwack bandmate, Brian MacLeod, who was fighting cancer and undergoing treatment at a Houston medical clinic.

On May 24, 2010 the band members (Bill Henderson, Ed Henderson, Doug Edwards and Jerry Adolphe) were joined by former members Roy 'Bim' Forbes, Ab Bryant and Claire Lawrence, plus Howard Froese's son Tyson on acoustic guitar (standing in for his father, who had died of cancer in the mid-1990s), and Collectors singer Howie Vickers for a Chilliwack 40th Anniversary show at the River Rock Show Theatre in Richmond, British Columbia.
