hi everybody!

I'm completely new here, so again: hi everybody!

I really need the help of someone with a good musical hearing. I want to play the song "sister anne" by MC5 with my band, but I can't figure out the the rythm chords.

If you don't know the song:


It's pure Rock 'n' Roll if you ask me!

The main chord during the verse seems to be an E powerchord, but everything from there just sounds wrong. Did they maybe play it in an alternative tuning? Plus there seems to be some kind of modulation on top which i can't figure out.
I'm really lost...

Thanks in advance!
