nice interview with Geddy and Alex, that is around 50 minutes long. I hadn't heard about the fact on "The Wreckers" Geddy and Alex switched instruments.
The Smashing Pumpkins opening for Rush? as much as Billy sounds genuine and likable enough for that idea, I'd be rather surprised, at least in a full-scale tour, if that happens.
Of course personally, I'd love to see any number of other bands open for Rush, but I've come to believe it'll never happens as Rush along with their fans, enjoy the "Evening With" format a bit too much.
