The Guess Who play their final concert at a show in Montreal. Core members Burton Cummings and Randy Bachman would return for another tour in 1987. As time went on, a deep rift would develop between Cummings and drummer Garry Peterson, who continued to use the band’s name with new players. In 2023, Cummings and Bachman would file a lawsuit to keep Peterson from using their images in ads and posters.
