Just my interpretation, feel free to comment with corrections. The song is in E major and the tempo is about 84. Most of the song follows the chords E, G#, C#, A. Bo seems to improvise a bit with structure while maintaining this chord progression, so I'd say knowing the intro/chorus and then playing around with those chords for the verses are your best bet.
