I have tabbed out the entire song, in case you are a lazy guitarist, just like me.
The other version uses Ab in the main line (Today has been ok) in place of Fm, which, in 
my very humble opinion, might be incorrect.
But the tab for the intro bit is spot on, and i wont copy that here. :)

INTRO – Bb

Bb                   Gm
Friends tell me it's spring
Bb                   Gm
My window show the same
Bb                       Gm              Bb               Gm
Without you here the seasons pass me by
Eb                       Bb
I know you were not new
Eb                        Bb
That loved like me and you
Eb                  Bb
All the same I miss you
Fm                     Bb
Today has been ok
Fm                     Bb
Today has been ok

Fill – Bb

Bb                   Gm
The preacher lost his son
Bb                   Gm
He's known by all in town
Bb                       Gm              Bb               Gm
He found him with another son of God
Eb                        Bb
Feeding on the prayer
Eb                        Bb
Nevermind what God said
Eb                        Bb
But love had lost its cause
Fm                     Bb
And I thought today had been ok
Fm                     Bb
Today has been ok
Fm                     Bb
Today has been ok
Fm                     Bb

Fill – Bb


Bb                   Gm
Wind has burned your skin
Bb                   Gm
The lovely air so thin
Bb                       Gm              Bb               Gm
The salty water's underneath your feet
Eb                        Bb
No one's gone in vain
Eb                        Bb
Here is where you'll stay
Eb                        Bb
'Cause life has been insane but
Fm                     Bb
Today has been ok
Fm                     Bb
Today has been ok
Fm                     Bb
Today has been ok
Fm                     Bb
Today has been ok
