Sublime - Zimbabwe acoustic

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 Every mans gotta right to decide his own destiny Ab ''' C#m A And in this judgement there is no partiality Ab ''' C#m A And soon we'll find out who is the real revolutionary Ab ''' C#m A And I don't want my people to be tricked by mercenaries Ab ''' C#m A No more internal power struggle Ab ''' C#m A We come together to overcome the little struggle Ab ''' C#m A And soon we'll find out who is the real revolutionary Ab ''' C#m A And I don't want my people to be contrary Sorry about the "'''" but I have no clue what its called If you could understand this tab then you can probably play the song then I hope this helped out
