“Weird Al” Yankovic - Smells Like Nirvana

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 Don't know, don't know, don't know 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 oughta bug your parents Yeah It's unintelligible I just can't get it through my skull It's hard to bargle, dargle, fftouth 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 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, never mind Don't know, don't know, don't know, oh no Don't know, don't know don't know 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 Ayaah!
