The band is from Winnipeg, Canada. They began as Al And The Silvertones and were heavily influenced by British musicians. They went on to become one of the biggest bands in the history of Canadian music, and the first Canadian Rock band to achieve success in the US without leaving Canada. (thanks, Bertrand - Paris, France)
They have a star on Canada's Walk Of Fame, but haven't been inducted into the Rock And Roll Hall Of Fame.
Bachman is a devout Mormon. His religious beliefs led him to quit the band in 1970 and formed his own group, Bachman-Turner Overdrive. His bantams resented this because it broke them up at the height of their popularity.
The band was known as Chad Allen And The Expressions when they released their first album in 1965. As a promotional gimmick to imply that they were a hot British import, their first single, a cover of "Shakin' All Over
" by Johnny Kidd & the Pirates, was issued with only words "Guess Who?" on the label. Disc jockeys thought that was the group's name, so it stuck.
Bachman has 8 children. His son, Tal, is a pop singer who had a hit "She's So High" in 2000.
In 1970, they sold more records worldwide than any other band.
They reunited in 1999 when the Premiere of Manitoba asked them to play at the closing ceremonies of the Pan Am Games in Winnipeg. They had such a great time that they launched a North American tour the next year.
Various versions of the band continued to tour starting in 1979. The only constant through all those years was Kale. By 1989, Peterson had also returned.
Allan and Bachman reunited after Bachman left the group and recorded a few albums as Brave Belt.
Burton Cummings was in another Winnipeg band called The Deverons when he was asked to join The Guess Who. He started off as their keyboard player, but took over on vocals when their lead singer Chad Allan quit to return to school. Cummings had dropped out of high school and was just 17 when he was asked to join the band.
Allan became the host of the Canadian TV show Where It's At. In 1968, his former band landed a regular spot on the show.
The group has re-formed from time to time in various incarnations. By the mid-2000s, Peterson and Kale had gained control of the band's name and performed as The Guess Who without Bachman or Cummings.
Their 2000 tour was called the "Runnin' Back Through Canada" Tour. They started in Newfoundland and played at least one concert in every Canadian province. The concert in their home town of Winnipeg was played in pouring rain and is available on DVD, entitled Runnin' Back Through Canada. The lineup on this one was original members Randy Bachman (guitar), Burton Cummings (vocals) and Garry Peterson (drums), joined by Bill Wallace (bass) and Don McDougal (guitar). Wallace and McDougal have been intermittent members since the early '70s.
In 2001, they were doing a summer tour in the US and were in New York on September 11 for a concert in New Jersey the next day. The Jersey concert was, as expected, canceled. (thanks, Tony - Rockville, MD, for above 2)
Bachman left the group shortly after their biggest hit, "American Woman," started climbing the charts. He explained to Melody Maker in 1974: "We were on the road for a 93-day tour and many things were bothering me, the lousy hours and the rotten food, and I became very ill. I had gall bladder trouble and I was vomiting every night and I hadn't a clue what was wrong. Finally I got the group together and told them that after ten years I felt like I was dying. They hired a temporary replacement and I spent two or three months in hospital."
