During their most successful period, the Guess Who released eleven studio albums, all of which reached the charts in Canada and the United States. Their 1970 album American Woman reached number 1 in Canada and the United States, while five other albums reached the top ten in Canada. The Guess Who charted fourteen Top-40 singles in the United States, and more than thirty in Canada.
The Guess Who officially disbanded in 1975, though several periodic reunions took place over the years. An unauthorized version of the band organized by former bassist Jim Kale toured and recorded under the Guess Who name for several decades, often performing without any original band members on stage. After a lengthy legal dispute, the band's primary songwriters, guitarist Randy Bachman and frontman Burton Cummings, regained control of the Guess Who name in a 2024 settlement, and toured in 2026 with a new lineup.
