Garth Brooks surprised the crowd at Nashville's Bluebird Cafe on Monday night (Oct. 3), stopping by to perform a few acoustic tracks at the iconic venue.

Brooks spent Monday morning in Nashville announcing a free show at Music City's Ascend Amphitheater in celebration of his seventh diamond-certified album. That evening, during his weekly Inside Studio G live chat on Facebook, the country superstar was dropping hints about where he was headed, revealing at the end that he was about to surprise some songwriters at a MusiCares event at the Bluebird.

Fans at the show shared videos of Brooks' performances on Instagram and Facebook; photos show Brooks greeting fans outside the venue and his wife, Trisha Yearwood, spending some time onstage as well. Readers can press play above to watch Brooks and songwriter Kent Blazy perform "If Tomorrow Never Comes," which became a No. 1 hit for the pair in 1989; below, press play to see Brooks sing "The Dance."

On Sept. 21, Brooks’ 2007 The Ultimate Hits collection became his seventh release to reach diamond status — that is, to have sold 10 million copies; the other six albums that have helped him reach his historic diamond status are No Fences, Garth Brooks, Double Live, Sevens, The Hits and Ropin’ the Wind. Brooks now has more diamond records than the Beatles.

Brooks is currently on the road for his World Tour with Yearwood; the trek began in 2014 and is scheduled to wrap up almost three years later, sometime in 2017. In addition to his tour, Brooks recently launched his own channel on SiriusXM and played his first-ever show at the Ryman Auditorium to commemorate the event.
