I thought of Roman's post here when I saw an article recently about Cummings, Bachman, and the latest version of The Guess Who. Here's what it says about the other musicians who are touring with them. 

But both Bachman and Cummings warned that this version of the Guess Who is unlike any other.
They’re returning with a fuller sound — a seven-man lineup that includes musical director and bassist Jeff Jones and two other guitarists. The adjustments are allowing the Guess Who to perform rarities from their experimental days.
“They’re deep cuts,” Cummings said. “The real followers know these songs. We’re doing ‘969,’ a guitar instrumental from the ‘American Woman’ album, which we never did back in the day because it was just Randy, and he did all his parts in the studio. We never could do it live. I’m glad we’ve got a guitar army now and Randy’s out there leading the charge.”
