Here is my rendition of Rearviewmirror.  Watching the SNL performance, 
 this verified to me that I'm playing it at least close to right.  I don't
 include any of the solos, but those are pretty simple...  I also don't
 include any timings in the chord progression, since it's kinda repetitive
 anyway, and just listening to the song you should be able to figure out 
 what is going on.  During the 'verses', where I have (e f) in parenthesis,
 just pick those notes, not the chords (just lift your barre on the F#m to
 play the E note and the F note).
 
 This is what I call the "riff" below in the chord progression.
 It's the same fingering over and over, and the chord change during
 the riff is just moving the pattern up a step.  All notes are 8th notes,
 at about 100-120 bpm.  The first two notes (the fretted 'a' and the open
 'a') seem odd, but if you listen to the album's intro, he's definately 
 doing this, since the first two notes are not the same string.  The \/
 symbol below the tab is a hammer-on.  All the rest of the notes are 
 picked.  I divide the riff into two parts, the first being part 'A' and
 the second being part 'B'.  Part 'A' is played over the 'A' chord during
 the verses, part 'B' (when the chord changes during the riff) is played
 over the 'B' chord.  Just play each part however many times it is in the
 song.  As you will see, the riff is exactly the same pattern, moved up a
 step.
