Alex Lifeson was a guest on the Craig Charles show on BBC 6 Music earlier this afternoon, and spoke a bit about Rush's legacy, Envy of None, and more. At one point Craig asked him about he and Geddy playing together at the South Park 25th anniversary show and what - if any - implications that might have for the pair working together as Rush or something else in the future:

Well, I don't think so [as Rush]. 41 years of touring together, not only just as a unit, but as friends and brothers - we can't even develop another version of that. I don't know. Geddy and I are best friends. We've always been best friends. We loved doing the South Park thing. It was the first time we'd played together in 7 years. I wouldn't be surprised if we did something together in the future, but I wouldn't be surprised if we didn't. We're having dinner together on Sunday. Life is many different things, and music - for us - as Rush was one [thing], and that's over now. If something comes of it - great. We're gonna do a couple of other gigs. We're gonna play in London at the Taylor Hawkins tribute on September 3rd. So we're looking forward to that. Then we're gonna reprise that at the end of September in Los Angeles. So we're joking [about this] being our new tour. It started with the South Park thing - that was the first leg. The second leg is in a month from now, so we have 3 weeks off to rest after this last difficult gig of doing one song. So we're having fun with it. It's in our blood, but I don't know where it goes from here.

So Alex is as coy as usual regarding Rush continuing in some shape or form, but he did seem to confirm that he and Geddy will be performing (not just appearing as special guests) at the Taylor Hawkins tribute shows next month. You can listen to the entire interview online here, with the Alex interview coming in starting at the 1 hour, 6 minute mark and lasting for a total of 20 minutes, including Craig playing Limelight and Enemy (Envy of None song).
