If you're a famous person, you've probably performed this year with our cover girl Taylor Swift.

She's brought up Justin Timberlake, Mick Jagger, John Legend, a fictional character from Friends, Marshawn Lynch, Pope Francis, John Boehner, the ghost of John Lennon, the roof of the Sistine Chapel, and the Super Harvest Blood Moon. But we DARE YOU to find a bigger fan than Steven Damn Tyler, who joined Taylor onstage for the crashing-asteroid ballad "I Don't Want to Miss a Thing" while in Nashville recording his country album, which is nearly finished and due next year.

We caught Tyler in his post-Swiftian glow.

So Pump came out in actual 1989. You guys were already staging a comeback.

Lifespan, right? She told the audience that's when she was born, and I was like, "Wait, whaaaaaaat?" My God, I got ties older than that!

When she was a fetus, she already had 20 years of Aerosmith records to catch up on!

I thought she named it that because she was being quirky! Like if we called our new album 1971 because that's when the band started. I kind of base my life on albums—what year was Rocks, what year was Get a Grip, and what year was Pump, what year was Toys in the Attic. 1989 was such a big year for Aerosmith.

She doesn't seem like your average 25-year-old, does she?

She is an incredible entity—it's unreal what that woman is. She reminds me of the wonder around Madonna. Your average person thinks Madonna's singing "Like a Virgin," but if you look at what she endured in this man's-world music business of ripoffs, scoundrels, and bastards, she's doing it like that. She's a phenomenon.

She's like a beautiful guitar that's got beautiful strings, and when they're strummed they sing these notes, but if you lean it up against the amp it starts feeding back. If you lean Taylor up against her audience—and she's singing and they're screaming—it's a complete circuit. It's like a feedback loop.

Were you expecting that kind of reaction from her fans?

Well, I don't wake up in the morning and go, "Oh, my God, I'm Steven Tyler," but I walked onstage in front of a bunch of 16-year-olds, and they were all singing the lyrics at the top of their lungs. It was a real moment.
