savannah did an outstanding cover of this song on youtube and these are the chords she 
used, she did some odd D-chords and i'm not exactly sure what they are called but i'll 
tab them for ya

e|--3--4-------------------------------|
B|--4--4-------------------------------|
G|--5--5-------------------------------|
D|-------------------------------------|
A|-------------------------------------|
E|-------------------------------------|

*only play ^^ those chords where it says (D chords) where just says "D" play a regular D.
*Savannah picks most of the song, you can listen to the video, it's a pretty 
simple picking pattern.
*Enjoy
