D          Bb                      F
Come up to meet you, tell you I'm sorry

You don't know how lovely you are.
D          Bb                  F
I had to find you, tell you I need you,
            Fsus4
Tell you I set you apart.

Tell me your secrets and ask me your questions,
            Fsus4
Oh lets go back to the start.
D             Bb               F
Running in circles, Comin' in tails
             Fsus4
Heads on a science apart.

Chorus

Bb     Bb                F

D            Bb                     F
I was just guessin' at numbers and figures,
             Fsus4
Pulling the puzzles apart.
D              Bb                   F
Questions of science, science and progress
                 Fsus4
Don't speak as loud as my heart.

D                Bb                     F
And tell me you love me, come back and haunt me
          Fsus4
Oh and I rush to the start.

Runnin' in circles, Chasin' tails
        Fsus4
Comin' back as we are

No one ever said it would be so hard.

I'm goin' back to the start.
