Patrick Stump - This City chords

Capo 2


My computer is really slow so im just going to summarize it.
[ Tab from: http://www.guitaretab.com/p/patrick-stump/283637.html ]
Basically there is one pattern throughout the entire song. The pattern is
-> G, D, Am, and Bm.

Just switch chords to the beat. This shouldn't be too hard to do, i figured it out just 
by playing random notes.

Btw, this is my first tab/chords thingy so be nice.
