What is this song all about?

Can't figure any lyrics out

How do the words to it go?

I wish you'd tell me, I don't know

Don't know, don't know, don't know, oh no

Dnn't know, don't know, don't know

CHORUS

Now I'm mumblin' and I'm screamin'

And I don't know what I'm singin'

Crank the volume, ears are bleedin'

I still don't know what I'm singin'

We're so loud and incoherent

Boy this oughtta bug your parents

Yeah

It's un-in-tel-ligible

I just can't get it through my skull

It's hard to bargle nawdle zouss(?)

With all these marbles in my mouth

Don't know, don't know, don't know, oh no

Don't know, don't know, don't know...

CHORUS

Well we don't sound like Madonna

Here we are now, we're Nirvana

Sing distinctly? We don't wanna

Buy our album, we're Nirvana

A garage band from Seattle

Well, it sure beats raising cattle

Yeah

And I forgot the next verse

Oh well, I guess it pays to rehearse

The lyric sheet's so hard to find

What are the words? Oh, nevermind

Don't know, don't know, don't know, oh no

Don't know, don't know don't know...

CHORUS

Well, I'm yellin' and we're playin'

But I don't know what I'm sayin'

What's the message I'm conveyin'?

Can you tell me what I'm sayin'?

So have you got some idea?

Didn't think so, well, I'll see ya!

Sayonara, sayonara

Ayonawa, adinawa

Odinaya, yodinaya

Yaddayadda, yaaahyaaah

Ayaaaaah!
