The Guess Who is a Canadian rock music band from Winnipeg, Manitoba that was one of the first to establish a major successful following in their own country as well as abroad in the late 1960s and early 1970s. They were the first Canadian rock group to have a No.1 hit in the United States (“American Woman,” 1970). The band evolved out of Chad Allan and the Impressions (also shortened to The Impressions), a British Invasion styled band fronted by Chad Allan and featuring guitarist Randy Bachman. After their cover of “Shakin’ All Over” sold well as a single, their record label released their album with “Guess Who?” written on the cover, hoping to mislead unsuspecting buyers into thinking it was a British band. The name stuck, however, and from then on they were The Guess Who.
