Originally by Operation Ivy, there is a reason Green Day brought fans up on stage to take over on the instruments on this one so many times…it’s super easy! However, Green Day’s studio version is much slower and funkier than the Operation Ivy version (and marginally different than how they now perform it live).

Here is all you need to know to play along with Green Day’s recorded version of Knowledge:

D7, C7, G7*

Got that?

Want to play the Op-Ivy version? Easy, just lose the 7′s on those chords. Voila!

*I recommend barre chords. Sounds better than open (and is true to the recording).
