Miley Cyrus delighted her concert-going fans when she announced during her Ecuador show that she’d be doing a special song. “I want to be able to do the music that inspired me and made me want to be here on this stage tonight,” she announced.

“This song is something I always sing with my little brother… so this song is also for him.” And the crowd went wild, screaming with hysteria in anticipation of…perhaps some light country music fare? Maybe something from Miley’s childhood (such as it was), a ditty from the Jewel or Sheryl Crow songbook? Or perhaps a country standard by a legend like Patsy Cline?

Nope. Miley’s band began playing the opening strains of Nirvana’s “Smells Like Teen Spirit” instead, a grunge rock anthem that was released in 1991, one year before Cyrus was born. Watch the performance in the video above.
