ok, this is summer romance, the intro bit is taken from the live acoustic
version, thought it might be a bit easier to interpret without the effects
everywhere.

standard tuning

|-7h10-7-5h7--------7h10-7-5h7--------
|-7h10-7-5h7-7-7h10-7h10-7-5h7-7-7h10-
|------------6-6---------------8-8----
|-------------------------------------
|-------------------------------------
|-------------------------------------

that sequence is repeated a few times, then

|-7h10-5h7----------
|-7h10-5h7-7h10-5h7-
|----------6----4---
|-------------------
|-------------------
|-------------------

then back to the first sequence a few times, and after

|-7h10-7-5h7-7-7-7-7-7-
|-7h10-7-5h7-7-7-7-7-7-
|----------------------
|----------------------
|----------------------

then this is the break between that and the verse
(worked out thanks to my guitar teacher)

|-7-10-7---------------------------
|--------9-------------------------
|----------7-9-7-------9---7-9-7-7-
|----------------6-6-9---6---------
|----------------------------------
|----------------------------------
|----------------------------------

|-7--10-12-14-12-10/12-10-7-7-
|-7--x--x--x--x--x-----x--x-x-
|-7--7--9--11-9--7-/9--7--4-4-
|-7---------------------------
|-9---------------------------
|-7---------------------------

|-7-7-7-7--7-
|-7-7-7-7--7-
|-7-7-7-7--7-
|----------7-
|----------9-
|----------7-

repeat the sections, do up strums of the Bm7 chord for the bit tabbed above.

chorus

|-7---------6----7-------
|-8----7----5----7----12-
|-7----6----6----7----11-
|-9----7----5----9----12-
|-7----5---------9----10-
|----------------7-------

obviously strum those chords, then the 2nd time played them, end on the Bm chord
(2nd last)

then the little bit inbetween the chorus and the intro riff thing.

|-----------------------------
|-----------------------------
|-7-7-7-7-7-7-7-7-------7-6-4-
|-7-7-7-7-7-7-7-7-4-2-4-7-6-4-
|-5-5-5-5-5-5-5-5-4-2-4-5-4-2-
|-5-5-5-5-5-5-5-5-2-0-2-------

that's basically most of the song minus a few of the fills, which I really don't
know, and the intro in the studio/album version may have a different intro, but
some1 has already tabbed that out which was a decent version
