I got these chords after watching them play this live
(https://www.youtube.com/watch?v=oL9KueYZHRw). It doesn't match the recorded version 
exactly, but it's definitely a match
for the live one. It actually sounds better, in my opinion.

The chords are written in the most common version, but I added in optional fingering
variations for better notes and more accuracy. Either version works.

Enjoy!

It was our first week

Nothin' to do

So, let's just stay right here

G                             Cadd9

Dsus4        G
Right then I knew

When I looked at you
