is taken from the youtube video, all you have to do is search for it.

Intro/Verse: Guitar I - Charlie Simpson.

|----------|
|----------|
|--11--7---|
|--11--0---|
|--9---0---|
|--9---0---| (Could be 99911 - not too sure)

Rhythm is easy to figure out.

Lead - Verse - Unsure.

|-------------------------10------|
|-11--11--9--11--11--11--9--11----|
|---9---9--9---9---9---9------9---|

Repeat this throughout verse. This is only for the verse.

Chorus:

|----------|
|----------|
|--9----7--|
|--7----0--|

|--7----0--|

Repeat verse and chorus.

Then one more verse - strum the verse chords once each

Really easy. I'm fairly sure it's right, I guessed it just from watching the video, and 
I'd submit a tab just in case people wanted to learn it.

Comments are appreciated! Cheers!
