               ( intro )

D
Some people are down and now,

A
Some people are lonely now,

C                         G
Some people just need a vacation,

D
Some people can't fight a smile,

A
For some people it's been a while since,

C                           G
They had an all night conversation

Em
Since you walked into my life,

G
Everything's felt so right


D
The sun's been shining,

A
And I've been singing

C
This song in my head and it goes

G
Lalalalalalalala

D
Nothing but blue sky

A
When I stare into your eyes

C                      G
I get tongue tied everytime


You smile

Em
Some people don't know

              C
What love can do

                              G
Well, they should see me with you

D
I remember how we used to be

A
I remember how I used to dream

C
For someone to come along

                    G
And sweep me off of my feet

     Em
Some people say wishes don't come true,

G
Well I say some wishes do

D
The sun's been shining,

A
And I've been singing

C
This song in my head and it goes

G
Lalalalalalalala

D
Nothing but blue sky

     A
When I stare into your eyes

C                      G
I get tongue tied everytime


You smile

     Em
Some people don't know

     C
What love can do

                              G
Well, they should see me with you


Em                    C
And when they look at us,

                         G
They can tell, we're in love,

                A
Oh, it's so obvious


D (once)
The sun's been shining

A (once)
And I've been singing

C (once)
This song in my head and it goes

G (once) G (once)
Lalalalalalalala

D
Nothing but blue sky

     A
When I stare into your eyes

C                       G
I get tongue tied everytime


You smile

     Em
Some people don't know

              C
What love can do

A
Oh-Oh

     Em
Some people don't know

              G
What love can do

                              D
Well, they should see me with you

A
Oh Oh Oh Oh Oh Oh

   C         G
Me with you


Enjoy :)
