This is my tab of the guitar part Jamie plays in the acoustic video of Blunt Magazine Sessions.
http://www.youtube.com/watch?v=7XxYYyecU2c

The song is pretty straight forward. These are the parts played, not everything is 
correct but you can play the entire song with these tabs. Jamie improvises sometimes, just 
fool around and play what sounds good.

Keep in mind that the song switches to 3/4 time in the riff/bridge part. Play one 4/4 
bar with muted strings after both parts to keep in time.

The rhythm part consists of the power chords C5, G4 and E5, just follow the root notes.

As a final note I'd like to add that Jamie hits the open G and B strings quite a lot. 
This adds a lot to the sound, try it out.
