This is my first tab.  My Favorite Song by David Gray.  Super easy to sing along too.  I 
charted out the whole thing, but in general, you are usually playing one of the two progressions:

G5 , D5 , C5 , A5
E5 , D5 , C5 , A5

For variety, go ahead and switch the order of C and Am every now and then.

Cap on 1st Fret


G5
Come on, come on, come on
                  D5
come on, come on, come on
C5
Come on, come on, come on
                  A5
come on, come on, come on

      G5
The stolen glances, broken threads
      D5
The visions looming in our heads
      C5
The years spent running parallel
     A5
To everything that might of been
    G5
No longer possible to hide
    D5
The feeling welling up inside
      C5
Ain't never been this close before
            A5
Ain't never felt so far away

       G5
When a moment
  D5
A moment changes everything
       C5
When a moment
  A5
A moment changes everything
       G5         D5            C5
When a moment, it changes everything

     G5
The summer sky is blushing pink
      D5
The heart is running out of sync
      C5
Could this just be the day, I think
      A5
When anything is possible
      G5
Well, hey now you've been here before
   D5
To see your face and slam the door
    C5
And waiting for the floor to drop
 A5
Feel like time is standing still

       G5
When a moment
   D5
A moment changes everything
       C5
When a moment
   A5
A moment changes everything
       G5
When a moment
    D5
A moment changes everything
       C5
When a moment
  A5
A moment changes everything
        E5         D5             C5
When a moment, it changes everything

G5
Come on, come on, come on
                  D5
come on, come on, come on
C5
Come on, come on, come on
                  A5
come on, come on, come on

G5
Come on, come on, come on
                  D5
come on, come on, come on
C5
Come on, come on, come on
                  A5
come on, come on, come on

   E5         D5
A moment, a moment changes everything
   C5          A5
A moment, a moment changes everything
   E5         D5
A moment, a moment changes everything
   C5         A5
A moment, a moment changes everything

     E5        D5
Then moment, a moment changes everything
  C5                 A5                  E5
A5 moment
