Ok then... well this is my first tab and I felt I had to do this because there are no 
tabs for this song.....

Here's how I believe its played.....
I'm 99% sure this is correct...
I've played along with the song many times and it fits pretty well


I could not for the life of me find the name of the fourth chord listed
If you know help me out here

A:       577655
Ab:     466544
C#m: 446654
???:   244322
Bb:     799877


Well anyways the strumming I'll try to explain this
(its better to listen to the song)
is a downstroke,tap the strings,downstroke,upstroke

Listen to the song to figure out the small details like where he plucks the strings on 
A's and such....etc..etc...


Intro: A, Ab, C#m, A, Ab, ???, C#m, A

 Ab                           ???          C#m                   A

        Ab                    ???             C#m             A

Ab                    ???                C#m                  A

 Ab                    ???                C#m                  A
And soon we'll find out who is  the real revolutionary
