Intro: just hold the D chord 'til vocals start (I like to play some D sus variations and / or pick the notes
of the chord)

D
One One touch can fill a life of longing
                              Em

And when you're running for cover
         Em                      D
And you feel the sky falling down upon you
                         C

One word to fill a room of silence
                         Em
A hand to offer you some guidance
G                       D
Yeah - All you need is One

A moment long enough to notice
                               F
That everything's stepped into focus
G                       D

And when you've running from questions
        Em                        D
And it seems like uncertainty controls you
                          C
And when you looking for answers
        Em                    D
In the eyes of somebody who knows you

      C                   G
Then one is all that you need
