the majority of the ska parts of the song are a ska rhythm that goes G G C C and so forth. the only exception is right before the trombone solo, the section goes G G Bb Bb. Real difficult, I know. the first rock section goes: G Bb G Bb then it goes: C D G C C D the second rock section goes: A D A D E A the only other deviation from the G G C C ska part is where, real slowly, Aaron sings "Nowadays, the songs..." For that, strum a full C and D chord at the appropraite parts. cra (guitartabs.cc)
