'Nasty turn' in Guess Who fight sees Burton Cummings cancel agreements that let band perform his songs

Winnipeg music historian John Einarson said it's an unprecedented move that shows the fight between Cummings and the band has "taken such a nasty turn."

Last year, they filed a lawsuit accusing former bandmates Jim Kale and Garry Peterson of deceiving fans with a band touring under the Guess Who name.

Last year, Cummings and Bachman filed a lawsuit accusing Kale and Peterson of deceiving fans with a band touring under the Guess Who name.

But in their own court filing, Kale and Peterson argued they've always been upfront about the band's numerous member changes and have never advertised Cummings and Bachman as being part of the current lineup.

Cummings confirmed the move in Thursday's Rolling Stone story, saying the band will be sued every time they perform a song he wrote.

Several shows in Florida and Alabama have been cancelled since the band found out about the terminated agreements last Saturday, on a day they were expected to perform, Erwin said.
