This is taken from the version on the Man at Work album. The original was on the 
sons album which I have not heard, so I'm not sure if/how it differs.

Standard tuning:

Chords used:

D - XX0232
G - 320033
A - X02220
Bm - X24432
C - X32010

Intro: D - G

There is a little riff which is done on a guitar and a piano (there are 2 guitars at 
in this song) in the intro, and at other points in the song too, which goes:

e|-3-2-0-2-0---0----------------------------------------------------------|
B|-----------3---3-2-3-2-0-2----------------------------------------------|
G|---------------------------2-2------------------------------------------|
D|------------------------------------------------------------------------|
A|------------------------------------------------------------------------|
E|------------------------------------------------------------------------|


Also the little slide thing is used quite a bit throughout the song and in the into:

e|-------5-------------|
B|---5s7---5s3---------|
G|---------------------|
D|---------------------|
A|---------------------|
E|---------------------|

Play this before going into the verse:

e|----------------------------|
B|--------5s7-5-3s5-3---------|
G|----------------------------|
D|----------------------------|
A|----------------------------|
E|----------------------------|

Verse:

D                 G
Sometimes I wonder

Bm                  C
And sometimes I cry

D               G
I still go under

Bm                  C
And I don't know why


And I got


Chrous:

G                 A
A Storm in my heart

Bm              G
Tearing me apart

G                 A
Storm in my heart

          D
About you

And then back into the intro and a few of the riffs in that and back onto the verse and 
played the same way.

This riff is played after the second chorus:

e|--------------------------------------------------------|
B|--------------5-7----------------------5-7s10-----15-15-|
G|------5s7-7-7------4-2---------5s7-7-7------------------|
D|--------------------------------------------------------|
A|--------------------------------------------------------|
E|--------------------------------------------------------|

Thats pretty much it. There may be a few more slides dotted around, but they all keep 
the same strings/frets as the ones I've shown, so shouldn't be too hard to work them out. 
welcome.
