WATCH: Bruce Springsteen Joins Rolling Stones in Portugal's Rock In Rio Lisboa Music Festival

The minds of fans in attendance of last night's Rock In Rio Lisboa music festival were undoubtedly blown when New Jersey's own Bruce Springsteen joined the legendary Rolling Stones onstage for a performance. Together, the group played the Stones' 1972 track "Tumbling Dice."

We're curious if the song is one of the 64-year-old Springsteen's favorite Stones songs, considering he teamed up with the group for a performance of the same tune back in 2012 when they were playing in New Jersey as part of their 50^th anniversary tour.

Regardless, the 2014 performance is undeniably wonderful. Also, the amount of rock legend that stood upon the stage certainly didn't hurt either.

Last night's Stones show is in Lisbon was part of the band's 2014 tour, 14 on Fire Tour. It was put on hold back in March as a result of the unfortunate death of frontman Mick Jagger's girlfriend L'Wren Scott; however, the tour resumed this past Monday, May 26, in Oslo's Telenor Arena.

The continuation of their 2014 tour hasn't been the only call for celebration in Jagger's life as of late. Just last week, he found himself becoming a great-grandfather at the age of 70 when his granddaughter Assisi Jackson, 21, gave birth to a daughter.

In music, it seems age means nothing, because while the combined age of these guys easily exceeds 300, each of them rocked the house as if they were in their twenties.
