Nirvana - Mrs Butterworth Chords & Tabs

This is from the rehearsal demo on disc one of With the Lights Out.  
I'm not sure if it's standard or a half step down because the recording 
was transferred from the original cassette and is a little distorted 
and the speed is slightly altered due to compression and whatnot.  This 
isn't 100% right but it's better than the rest of the tabs on here.
