A Google Search turns up lots of results that suggest Nirvana did the song "I Smell Sex And Candy" but according to Wikipedia It was done by Marcy Playground and the article doesn't mention Nirvana. Did Nirvana do a cover of this song and if so where? If not, is there a reason this misconception is popular?
"Sex and Candy" came out in 1997. Kurt Cobain died in 1994. You can probably work it out from there. The misconseption exists simply because people think they sound alike.
Kurt Cobain died April 5, 1994 http://en.wikipedia.org/wiki/Kurt_Cobain
Sex and Candy by Marcy Playground released November 4, 1997 http://en.wikipedia.org/wiki/Sex_and_Candy
In an interview at songfacts Marcy Playground's John Wozniak says that
Yeah, where did I get the “sex and candy” part from? Well, I was dating a girl and she was going to Bryn Mawr College and it’s where my dad teaches. And I was probably 17 or something like that and she was like 18. I always liked the older girls. (laughs) But we were in her dorm room, and her roommate came in and she saw us there, and she was like, “Oh, it smells like sex and candy in here.” And I always remembered that. And that was back in the late ‘80s. And then when I was writing the song and I was coming up with all these weird disco-era references that I was making up, “platform double suede” and all that business, I was like, hey, let’s just throw in that phrase that’s been sticking in my head for the last 5 years or whatever. So I wrote that song in ’92, ’93, somewhere around there. And it didn’t really come out until ’97.
So according to the man who originally held the copyright claim the song wasn't recorded in a finished form until 1997. That makes it rather doubtful that Nirvana ever covered the song.
Additionally, all of the versions of "Sex and Candy" on youtube that are listed as being by Nirvana sound exactly like Marcy Playground's official video.
Kurt Cobain died in '94, and this song was written in '92 or '93. But there is NO WAY Kurt could have sang this song, because it didnt come out until it was released in 1997 first in February and then again in October. Sex and Candy is Marcy Playground. As someone else mentioned all the times that Nirvana is mentioned as who sang it, it is an error. I was 15 in 1997, I remember this song vividly. Lol
