The chords listed in the intro, verse, and outro can be misleading and seem overly complicated.
Simply put the intro, verse, and outro are played by finger picking the bottom 4 strings -
Bar the bottom 3 strings on the 7th fret, and walk down the D string starting with a B note (9th fret).
The chorus and bridge are played with bar chords.
