      C     A     G     F    Bb      D    Em
E|----0-----X-----X-----X-----X------0-----X----|
B|----1----13----12----10----15------3-----8----|

[Intro]
C Am G F G Am
Bb F G Am (x2)


[Verse]
C Am                     G              F     G   Am
 I decided to go out and breathe in the air I was made for
Bb     F                 G            Am
 There were ten thousand greys in the sky
C  Am
 Not a single soul around
 G            F        G  Am
 Seems no one likes to be rained on
 G            F           D
 Seems no one likes to be rained on


[Chorus]
          Em               F
 Come and flow wherever it takes you
             Am     G    Am
 Come on and flow


[Interlude]
C Am G F G Am
Bb F G Am


[Verse]
C Am
 And on the waterfront I walked
     G         F      G  Am
 The water was moving so graceful
Bb  F             G            Am
 I felt all of my fears fall away
C Am
 And I sat down and closed my eyes
     G            F          G  Am
 The sound on the breeze was my cradle
     G            F             D
 The sound on the breeze was my cradle


[Chorus]
          Em               F
 Come and flow wherever it takes you
             Am               G
 Come on and flow wherever it takes you
             Em               F
 Come on and flow wherever it takes you
             Am     G    Am
 Come on and flow


[Outro]
C Am                     G              F         D
 I decided to go out and breathe in the air I was made for
