You dont need a capo. This is my first one so any way i could make it better comment. 
Chords for the whole song
[G - D - Em - Cadd9]
 G
It's been a long year been a long night 
D
Took a shot at love for the first time 
Em
And I tried 
Cadd9
To keep it together inside 

G
So many hours too many days and months 
D
I'm still strugglin to give her up 
Em
I was reachin for a lifeline 
Cadd9
I was lookin for a good time

G
But there's a bleach blonde girl with the records on
D
And a smile on her face like she knows what's up 
Em
Whoa
Cadd9
Well if she don't care, then I don't care 

G
She's a new tattoo And I won't forget 
D
Her sun kissed skin 
Em
Shining on forever 
Cadd9
I don't wanna wait for the endless summer 
[G-D-Em]
I don't wanna wait, no I don't wanna wait (x3) 
Cadd9
For the endless summer 

Took her out, took in the moonlight 
Got lost in the stars in her eyes 
And I'm blinded by the light 

She was this and that and everything in between 
A secret word and I know the meaning 
How could I go for so long without her, yeah

But there's a bleach blonde girl with the records on
And a smile on her face like she knows what's up 
Whoa
Well if she don't care, then I don't care 

She's a new tattoo 
And I won't forget 
Her sun kissed skin 
Shining on forever 
I don't wanna wait for the endless summer 
I don't wanna wait, no I don't wanna wait (x3) 
For the endless summer 

~  [G - D - Em - Cadd9] ~

It's been a long year
Been a long night 
Took a shot at love for the first time 
I can't wait any longer, wait any longer 

But there's a bleach blonde girl with the records on
And a smile on her face like she knows what's up 
Whoa
Well if she don't care, then I don't care 

She's a new tattoo 
And I won't forget 
Her sun kissed skin 
Shining on forever 
I don't wanna wait for the endless summer 
I don't wanna wait, no I don't wanna wait (x3) 
For the endless summer 

I don't wanna wait, no I don't wanna wait (x3)
