This is my first tab. It's a very simple version of the song, and I'm quite sure it's 
how BLG plays it, but it sounds very right :)

Intro: C G Am F
                     C                          G
Little change of the heart, little light in the dark,
                     Am                   F
Little hope that you just might find your way up out of here.
                             C                         G
cause you've been hiding for days, wasted and wasting away,
             Am           F                         Am
but I got a little hope today you'll face your fears.
                   G                     Am

Take a chance and be strong,
                        Am                 F

                         G

  F                       Am                     G

                      F
