This song is in Eb (Eb Ab Db Gb Bb Eb) tuning. I added in one little thing, the open Bb and Eb strings before the 2nd chorus aren't actually in the song (but they're something that Brad used to do live occasionally). I'm a little sloppy on a few of the x357 chords in the outro, but you should get the idea.
