Intro: Dm  Am  G  
       Dm  Am  G  E

Am9          D9
One time, to know that it's real
Am9          D9
One time, to know how it feels
       G7+    E4  E
That's all

Am9           D9
One call your voice on the phone
Am9         D9
One place a moment alone
       G7+    E4  E
That's all

C                              Em
 What do you see, what do you know?
                    F
One sign, what do I do?
                C     G/B    Am
Just follow your lifelines through
                          Em
What if it hurts, what then?
                     F
What do we do, what do you say?
                 C/G   G        Dm   Am  G  
Don't throw your lifelines away
                               Dm   Am  G  E
Don't throw your lifelines away

Am9            D9
One time, just once in my life
Am9         D9                 G7+      E4  E
One time to know it can happen  twice

C7+/9           D9
One shot on a clear blue sky
Am9         D9                  G7+    E4  E
One look, I see no reason why we can't

C                 D
One chance to get back to the point where
G  D/F#        C   (G/B)
Everything starts
C             G/B         Am
One chance to keep it together 
     D              B7
when things fall apart
Am9         D9                    Em   E
One sign to make us believe it's true

C                              Em
 What do you see, where do we go?
                    F
One sign; how do we grow?
               C     G/B     Am
By letting your lifelines show
                      Em
What if we do, what now?
                         F
What do you say, how do I know?
             C/G    G          (Dm Am G...)
Don't let your lifelines go...
