- Taylor Swift's tour is packed with guest appearances
- Mick Jagger appeared in Nashville to perform a Rolling Stones hit with Swift
The two titans strutted down the stage's long catwalk and sang in unison on the classic 1965 single, with the impassioned rendition culminating in a call-and-response rave-up. As Swift eloquently summarized in a tweet following the performance, "*drops mic*."
Like Swift and Tyler's performance of Aerosmith's "I Don't Want to Miss a Thing" -- a collaboration that was sparked by a three-year-old tweet -- there is history between Swift and Jagger.
More than two years ago, during a June 2013 Rolling Stones concert in Chicago, Swift joined the band to perform their 1964 single "As Tears Go By."
"He's so cool," Swift told Access Hollywood of Jagger after that Chicago cameo.
"Getting that phone call, like 'Hey, would you like to go and play with the Rolling Stones?' Yes. That's an immediate yes. That is a bold, underline, exclamation point, yes."
Swift also called singing alongside Jagger "the best moment ever," a moment she got to relive on her own turf Saturday night.
However, Jagger wasn't the only musical guest on hand for Swift's final Nashville show: Leona Lewis also came out to perform her hit "Burning Love" with the 1989 singer.
