Task: Question Generation
Input (English): Passage: "Smells Like Teen Spirit" was first performed live on April 17, 1991 at the OK Hotel in Seattle, Washington. The performance is featured on the DVD of the 2004 box set With the Lights Out, while shorter clips are included on the Nevermind Classic Albums DVD, as well as the documentary film Hype! As the song's lyrics had not yet been entirely written, there are notable differences between it and the final version. For example, the first performance started with "Come out and play, make up the rules" instead of the eventual opening of "Load up on guns, bring your friends". A recording of the earlier version appears on With the Lights Out and again on Sliver: The Best of the Box. A similar early live performance of the song is found in the documentary 1991: The Year Punk Broke, filmed during a 1991 summer tour in Europe with Sonic Youth.
Nirvana often altered the song's lyrics and tempo for live performances. Some live performances of the song had the line "our little group has always been" changed to "our little tribe has always been", which can be heard on the 1996 live album From the Muddy Banks of the Wishkah. Rolling Stone remarked that the Wishkah version of "Teen Spirit" "[found] Cobain's guitar reeling outside the song's melodic boundaries and sparking new life in that nearly played-out hit". A notable alternate performance of "Smells Like Teen Spirit" occurred on BBC's Top of the Pops in 1991, during which the band refused to mime to the pre-recorded backing track and Cobain sang in a deliberately low voice and altered numerous lyrics in the song (for example, "Load up on guns, bring your friends" became "Load up on drugs, kill your friends").   Cobain later said he was trying to sound like former Smiths frontman Morrissey. When Top of the Pops was cancelled in 2006, The Observer listed Nirvana's performance of "Smells Like Teen Spirit" as the third greatest in the show's history. This performance can be found on the 1994 home video Live! Tonight! Sold Out!!.
