CAPO 7 (chords are relative to capo)

This version sounds like the live version with ukulele. 
 
INTRO: G  D  Em  C


    G
You have my heart
                   D
And we'll never be worlds apart
          Em
May be in magazines
                 C
But you'll still be my star
           G
Baby cause in the dark
              D
You can't see shiny cars
                    Em
And that's when you need me there
              C
With you I'll always share

C
Because

[Chorus]
                                 G
When the sun shines, we'll shine together
                      D
Told you I'll be here forever
                      Em
Said I'll always be a friend
                                        C
Took an oath I'ma stick it out till the end
                                G
Now that it's raining more than ever
                                D
Know that we'll still have each other
                             Em
You can stand under my umbrella
                             C
You can stand under my umbrella
                 G
(Ella ella eh eh eh)
               D
Under my umbrella
                 Em
(Ella ella eh eh eh)
                C
Under my umbrella
                 G
(Ella ella eh eh eh)
               D
Under my umbrella
       Em
(eh eh eh)

C
      G                             D
These fancy things, will never come in between
                  Em                 C
You're part of my entity, here for Infinity
                 G
When the war has took it's part
                   D
When the world has dealt it's cards
       Em                           C
If the hand is hard, together we'll mend your heart

C
Because

[Chorus]
