Hey this is a great song and i was surprised to find the waves of change tab up there so i thought add this!

   Em (022000@1)Em7    Am (x02210@1)    G (320003@1)     Ce---0-0-0---0-0-0---3-3-3---0-0-0--] (x32010@1)B---0-0-0---1-1-1---3-3-3---1-1-1--]
G---0-0-0---2-2-2---0-0-0---0-0-0--]
D---2-2-0---2-2-2---0-0-0---2-2-2--] Just play this through out.
A---2-2-2-0-0-0-0---2-2-2-3-3-3-3--]
E-0-0-0-0---------3-3-3-3----------]

And when he goes "Often times is difficult" just play Em and Em7.

Hope that helps 

Enjoi
