They're 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.
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 make people think they were a hot British import, the only words on the album cover were "Guess Who?" Disc jockeys thought that was their 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.
In 1966, they got their own television show, Let's Go, which ran for 2 years on The Canadian Network. (thanks, Bertrand - Paris, France)
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 band touring since 2000 consists of 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. All sing backing vocals.
The 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.
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.
