Hi! This is my first song that I've submitted. Hope it helps! 
 
To play it the way Jason does, CAPO ON 4TH. Also, the strum pattern is 

D-D-U-U-D-U (x2 per chord) 


The intro goes like this...
|------------------------------------|------------------------------|
|------------------------------------|------------------------------|
|-11/13-11~~11/13-11~~11/13-----8/9--|-11/13-11~~11/13-11~~11/13----|
|---------------------------13~~----9|---------------------------13~|
|------------------------------------|------------------------------|
|------------------------------------|------------------------------|

       G                       
Well you've dawned on me, you bet I felt it. 

    D                       
I tried to be chill, but your so hot that I melted, 

   Em 
I fell right through the cracks. 

          C  
Now I'm tryin' to get back. 


This chord progression continues throughout the song. I tried to give you and idea of it up there.
Hope this helps! Good luck! xoxo
