The other tab for this one said it was the full song, but it was missing some parts.
Main riff (this can be played in many positions, this is what I use).

2:21 (very approximate rythem; I'm not at all 100% on some of these chords, but they sound okay; play either a C or C6 - it doesn't really matter)

I hope that's not too confusing. That means play the first part once and play the second part (after the bar) 3 times.

For the rest of the song you can just play those 2 chords. If you want to solo, use A major pentatonic.
Well, there you go. Hopefully I didn't forget anything. Have fun.
