There's another tab by Jenn that's just a tad off in a few places, most noticeably in
the main riff and the 2nd guitar. I'm not sure how s/he ended up with the tab s/he did but
this is a little more correct. It's possible the other tab's listing pertains to a 
little later in the song but to my hears the riffs sound mostly the same the whole way
through. Much thanks to Jen though, this is largely just a touch up of s/he original post.

There are probably mistakes but I'm sure the main riff and the 2nd guitar are mostly
right. I am a complete novice at the guitar but this seemed easy enough to pick out. Email
me for corrections!
