Revolution is a classic song progression, made real.
First intro chords are just dreamy in its acoustic simplicity – then accompanied by the third chord to say ‘hi’.
This song is a ‘young lover-coulda/shoulda’ scenario vis-a-vie, longing and ‘we will prevail’ anthem. But it’s not too ‘sugary’, but just has enough tact to stay good and repeatable.
But yea, the intro acoustic chords are delicious.
