For a nice "open" feel I like using these chords:

E | ---0---0---0---0---0--- | 
B | ---0---0---0---0---0--- | 
G | ---6---4---6---8---(b9)-- | 
D | ---6---6---7---(b9)--(b9)-- | 
A | ---4---6---7---(b9)--7--- | 
E | ---X---4---5---7---0--- | 
    C#m Abm  A   B   E

C#m     Abm         A                B
Never before have I seen you look so blue
  C#m          Abm      A                Ab7
I can't find a cure and nothing comforts you
    A                       Ab7
The light at the end of the tunnel
        A                       B   B7
Doesn't shine at the end of the day


CHORUS
              E                     C#m
Everytime you cry, save up all your tears
               Abm                   B7
I will be your rainbow when they disappear
              E                    Abm
Wash away the pain, till you smile again
              C#m      B       A
I will be the laughter in your eyes
B             E   Abm   A   B
Everytime you cry


Time has a way of wounding what has healed
What can I say?  I know just how you feel
Your soul is dark and troubled
Like a river running wild


CHORUS


C#m      Abm                  A    B
Well you know that's what I'm here for
C#m    Abm                A    Ab7
I will give you what you need, more
         A          Ab7
There'll be no hesitation
       A         B    B7
I will reap no reward
