How to play "time of your life" by green day on guitar

The verses go G, C add9, D, Dsus4. Also the D to Dsus4 is a quick add on of the pinky just to give the song some flare. Those two chords put together only last as long as the G and C add9.

Verse: G, C add9, D, Dsus4.

The chorus goes: Em7, D, Dsus4, C add9, G and leading back into the verse goes Em7, D, D sus4, G. Same thing with the D to Dsus4 here. Those two chords last two beats each.

Chorus: Em7, D, Dsus4, C add9, G.
