1992 Nirvana appeared on NBC-TV's Saturday Night Live performing two songs, 'Smells Like Teen Spirit' and 'Territorial Pissings'. Also on this day the group's Nevermind went to No.1 on the US album chart.
1991 Nirvana recorded a performance for BBC TV music show Top Of The Pops in London. When asked to lip-sync 'Smells Like Teen Spirit' to a pre-recorded tape Kurt Cobain protested by singing an octave lower (he later confirmed he was imitating Morrissey from The Smiths), and attempted to eat his microphone at one point. He also changed some of the lyrics, exchanging the opening line "load up on guns, bring your friends," for "load up on drugs, kill your friends."
1993 Nirvana recorded their MTV unplugged special at Sony Studios, New York. Nirvana played a setlist composed of mainly lesser-known material and cover versions of songs by The Vaselines, David Bowie, Meat Puppets and Lead Belly. The album won the Grammy for Best Alternative Music Album in 1996.
