VIDEO : Taylor Swift, Mick Jagger Sing 'Satisfaction' in Nashville

Taylor Swift took the stage at Nashville's Bridgestone Arena for the second of two concerts there Saturday, and a night after bringing out Steven Tyler and Alison Krauss during the 1989 Tour stop, the singer this time welcomed Mick Jagger for a surprise rendition of the Rolling Stones' "(I Can't Get No) Satisfaction." 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*."
