Guys, it's a Meat Puppets song.

You're absolutely right - "Oh, Me", "Plateau" and "Lake Of Fire" are all Meat Puppets' songs. But tabs of these songs here are based on their acoustic performances by Nirvana on "MTV Unplugged in New York".
Basically we tend to use the name of the performer, whose performance was used in song tablature - it's equal to the song's author name in most cases, but there are some exceptions - like this one.

а чём базар

Yeah, but they can add this songs as Nirvana's,
since they played them for the unplugged...

lol, meat puppets versions are funny

yeah not only are those 3 songs by m.puppets but the two brothers chris and kurt kirkwood actually play the music ( w/ dave ghrol on drums) for those songs on the nirvana unplugged album. those three songs (originall versions) are all on "meat puppets II". If you are a nirvana fan i deffinatly recomend checking out the meat puppets.. they have like 30 albums but "no joke" "up on the sun" and "golden lies" are really good just to name a few...
