The chords in the song "Come as you are" by Nirvana are a slowed down replica of Killing Joke's 1985 song "Eighties." The songs were so similar that Nirvana considered holding off releasing the song as a single. Killing Joke considered legal action, but when Kurt Cobain died, they decided not to sue. ("It's a short f--king life, mate - we could be going fishing or something sensible," lead singer Jaz Coleman explained).
Dave Grohl is a big fan of Killing Joke and helped them out by playing drums on their 2003 self-titled album.
