Verse 2

Chorus

"Post Chorus" (2x)

Bridge- No bass until 2:35 which is just 5 fret (which is a D) on the A chord

Alt Chorus- same as Chorus


The way they actually play the verse is all on the A with a giant slide in there 
somewhere. So with that the verse would be:

A--5///13/15-8--5---13\\\3/8--

/=slide up  \=slide down
