The chords are A, E, and C#m. It's a really good song and it's easy! 
Capo 1st

A
 We roll in heavy summer when there's strength in our numbers
A
 And your breath's hot and gross but I kiss you like a lover
E
 Legs stick to the seats of the car someone grew into
E
 I forget the knowledge from the lessons that I went to.


A
 And Jamie picks fights but they're weak and short-lived
A
 Because no one can be bothered when it's humid like this
E
 And we roll in heavy summer like it's shameful to be underneath a ceiling or
 A roof,          
E
 Try come out and steal our thunder.

Instrumental:

A     E


A
 Now the days are getting cooler and the burning of our limbs 
A
 Doesn't happen quite as bad and the burn is just
E
 Skin-deep in the fantasies and dreams of the winter
E
 Like the movies that we watched to pretend it wasn't winter
A
 And everywhere we go I can feel a subtle taste of the deeds outgrown and the 
 welcome overstayed
E
 And you're no better at swimming than you were in the beginning but you come
 over at night and we practice all the breathing

A
 Go all the way,
A
 Have your fun, have it all
A
 This will take you down
E
 Get through the days
E
 Do your thing, do it well
E
 This will take you down.

A
 Go all the way
A
 Have your fun, have it all
A
 This will take you down
E
 Get through the days
E
 Do you your thing, do it well
E
 This will take you down.


C#m
 I'll pull the trick if I want to
C#m
 I'll pull the trick and it comes true
E
 I'm chewing gum and it's killing you
E
 We're getting dead and it's the right way to do it
C#m
 I see you happy in the front seat
C#m
 I see you with all of your front teeth
E
 You're allergic but you never said
E
 We're getting dead and it's the right way.
