Paul McCartney Tour: The Beatles Bassist Reflects on "Out There!" World Tour, Nirvana Jam

Paul McCartney is a huge draw on tour, and he still loves to do it. The former Beatles bassist recently did some recording in Seattle, where he invited former Nirvana members Dave Grohl, Krist Novolesic and touring guitarist Pat Smear onstage to rock out. McCartney did an interview with Rolling Stone where he discussed how much he still enjoyed playing old Beatles tracks, even the lesser known ones. 

"It's really fun," McCartney says of touring. "We've got a really good band. We're very happy with the show, 'cause we've honed it down over the years as to what we like playing and what we think the audience likes to hear. There's some stuff the audience doesn't even know - not many, I must admit, but a few little ones. So the show just seems to run itself now. I'm constantly amazed at it, actually. I get on there, do the opening things, and then suddenly I'm changing to electric guitar and I'm going, 'Oh, this is nice' - you know, I always like to plug in an electric guitar. Then I'm swapping guitars for 'Paperback Writer,' and I'm thinking, 'This is nice. I love this Epiphone Casino.' Then, just when it could get boring, I move to piano, and I think, 'Oh, this is cool!' I swap through instruments quite a lot, which keeps it nice and fresh for me."

McCartney says that fans shouldn't worry when this tour ends, because he has no plans to retire yet. 

"I can't imagine ever not doing it," he said. "It's what I do, and it's what I've always done, and I love it so much. Of course, there's got to be some kind of physical limitation. But I haven't found it. I mean, I did that show last night, and I'm thinking, 'Jesus, God, man. You know, you're not 25.' But then, my other side of my head's going, 'Yes, you are! Get on with it!' So I haven't found my physical limitation yet. If I do, then I'll have a think about the question. 'Til then, I'm ignoring it."
