The Guess Who

The Guess Who are a Canadian rock band from Winnipeg, Manitoba. Initially gaining recognition in Canada, they also found international success from the late 1960s through the mid-1970s with numerous hit singles, including "No Time", "American Woman", "These Eyes" and "Share the Land". Several former members of The Guess Who, notably Burton Cummings and Randy Bachman (of Bachman–Turner Overdrive), have also found considerable success outside the band.
