Today RollingStone.com posted an interview with Primus' Les Claypool, where he explained that this tour has been in the works for some time, before the the passing of Neil Peart:
“We’re trying to be very sensitive about doing the tour and not having it be, ‘Hey, all about Neil,’ ” Claypool says. “It’s about admiration for these amazing musicians and friends.”
"I talked to Geddy about it, yeah. I texted with him — I keep in touch with Geddy — just to make sure we weren’t trodding on something weird. So I checked in with him to see what he thought of it, and he was excited about the notion.
"He just got excited; he thought it was a great idea. You know, we go way back with those guys, so I think it made him feel good that it was going to be us that was going to do this thing. But I don’t know, you’d have to ask him. I can’t put words in his mouth, but he seemed excited about it."
