Alex Lifeson and Geddy Lee went to see the Primus show on Friday night last week in Toronto.
Of course the show featured Primus playing Rush's "A Farewell To Kings" album in its entirety.
They posted a video of them watching from the side of the stage on Instagram and wrote that Primus "Totally nailed it!"
"They did us proud and we thank them deeply for the tribute and the lasting friendship.”
Primus also shared a photo of the band with Lee and Lifeson on Facebook with the caption, "KINGS."
